Clement Attlee in the context of "Royal Commission on Capital Punishment 1949–1953"

The Potsdam Conference (German: Potsdamer Konferenz) was held at Potsdam in the Soviet occupation zone from 17 July to 2 August 1945, to allow the three leading Allies to plan the postwar peace, while avoiding the mistakes of the Paris Peace Conference of 1919. The participants were the Soviet Union, the United Kingdom, and the United States. They were represented respectively by General Secretary Joseph Stalin, prime ministers Winston Churchill and Clement Attlee, and President Harry S. Truman. They gathered to decide how to administer Germany, which had agreed to an unconditional surrender nine weeks earlier. The goals of the conference also included establishing the postwar order, solving issues on the peace treaty, and countering the effects of the war.

The foreign ministers and aides played key roles: Vyacheslav Molotov, Anthony Eden and Ernest Bevin, and James F. Byrnes. From 17 July to 25 July, nine meetings were held, when the Conference was interrupted for two days, as the results of the British general election were announced. By 28 July, Attlee had defeated Churchill and replaced him as Britain's representative, with Britain's new Secretary of State for Foreign Affairs, Ernest Bevin, replacing Anthony Eden. Four days of further discussion followed. During the conference, there were meetings of the three heads of government with their foreign secretaries, as well as meetings of only the foreign secretaries. Committees that were appointed by the latter for precursory consideration of questions before the conference also met daily. During the Conference, Truman was secretly informed that the Trinity test of the first atomic bomb on 16 July had been successful. He hinted to Stalin that the U.S. was about to use a new kind of weapon against the Japanese. Though this was the first time the Soviets had been officially given information about the atomic bomb, Stalin was already aware of the bomb project, having learned about it through espionage long before.

Herbert Stanley Morrison, Baron Morrison of Lambeth (3 January 1888 – 6 March 1965) was a British politician who held a variety of senior positions in the Cabinet as a member of the Labour Party. During the inter-war period, he was Minister of Transport during the Second MacDonald ministry, then after losing his parliamentary seat in the 1931 general election, he became Leader of the London County Council in the 1930s. After returning to the Commons, he was defeated by Clement Attlee in the 1935 Labour Party leadership election but later served as Home Secretary in the wartime coalition.

Morrison organised Labour's victorious 1945 election campaign, and was appointed Leader of the House of Commons and acted as Attlee's deputy prime minister in the Attlee ministry of 1945–51. Attlee, Morrison, Ernest Bevin, Stafford Cripps, and initially Hugh Dalton formed the "Big Five" who dominated those governments. Morrison oversaw Labour's nationalisation programme, although he opposed Aneurin Bevan's proposals for a nationalised hospital service as part of the setting up of the National Health Service. Morrison developed his social views from his work in local politics and always emphasised the importance of public works to deal with unemployment. In the final year of Attlee's premiership, Morrison had an unhappy term as Foreign Secretary. He was hailed as "Lord Festival" for his successful leadership of the Festival of Britain, a critical and popular success in 1951 that attracted millions of visitors to fun-filled educational exhibits and events in London and across the country.

Aneurin "Nye" Bevan PC (/əˈnaɪrɪn ˈbɛvən/; Welsh: [aˈnəɨ.rɪn]; 15 November 1897 – 6 July 1960) was a Welsh Labour Party politician, noted for spearheading the creation of the British National Health Service during his tenure as Minister of Health in Clement Attlee's government. He is also known for his wider contribution to the founding of the British welfare state. He was first elected as MP for Ebbw Vale in 1929, and used his Parliamentary platform to make a number of influential criticisms of Winston Churchill and his government during the Second World War. Before entering Parliament, Bevan was involved in miners' union politics and was a leading figure in the 1926 general strike. Bevan is widely regarded as one of the most influential left-wing politicians in British history.

Raised in Monmouthshire, in modern day Blaenau Gwent, by a Welsh working-class family, he was the son of a coal miner and left school at 14. Bevan first worked as a miner during his teens where he became involved in local miners' union politics. He was elected head of his Miners' Lodge when aged 19, where he frequently railed against management. He joined the Labour Party and attended Central Labour College in London. On his return to South Wales he struggled to find work, remaining unemployed for nearly three years before gaining employment as a union official, which led to him becoming a leading figure in the 1926 general strike.

The Churchill war ministry was the United Kingdom's unity coalition government for most of the Second World War from 10 May 1940 to 23 May 1945. It was led by Winston Churchill, who was appointed prime minister of the United Kingdom by King George VI following the resignation of Neville Chamberlain in the aftermath of the Norway Debate.

At the outset, Churchill formed a five-man war cabinet which included Chamberlain as Lord President of the Council, Clement Attlee as Lord Privy Seal and later as Deputy Prime Minister, Viscount Halifax as Foreign Secretary, and Arthur Greenwood as a minister without portfolio. Although the original war cabinet was limited to five members, in practice they were augmented by the service chiefs and ministers who attended the majority of meetings. The cabinet changed in size and membership as the war progressed but there were significant additions later in 1940 when it was increased to eight after Churchill, Attlee, and Greenwood were joined by Ernest Bevin as Minister of Labour and National Service; Anthony Eden as Foreign Secretary, replacing Halifax who was sent to Washington as Ambassador to the United States; Lord Beaverbrook as Minister of Aircraft Production; Sir Kingsley Wood as Chancellor of the Exchequer; and Sir John Anderson as Lord President of the Council, replacing Chamberlain who died in November (Anderson later became chancellor following Wood's death in September 1943).

The Big Three is a term used in the context of World War II to refer to the main powers among the Allies of World War II, and their respective leaders: Franklin D. Roosevelt of the United States, Winston Churchill of the United Kingdom, and Joseph Stalin of the Soviet Union. In 1945, Roosevelt and Churchill were replaced by their successors (Harry S. Truman and Clement Attlee), who are sometimes counted among the Big Three as well.

On 19 August 1953, Prime Minister of Iran Mohammad Mosaddegh was overthrown in a coup d'état orchestrated by the United States (CIA) and the United Kingdom (MI6). A key motive was to protect British oil interests in Iran after Mossadegh nationalized and refused to concede to western oil demands. It was instigated by the United States (under the name TP-AJAX Project or Operation Ajax) and the United Kingdom (under the name Operation Boot).

Mosaddegh had sought to audit the documents of the Anglo-Iranian Oil Company (AIOC), a British corporation (now part of BP), to verify that AIOC was paying the contracted royalties to Iran, and to limit the company's control over Iranian oil reserves. Upon the AIOC's refusal to cooperate with the Iranian government, the parliament (Majlis) voted to nationalize Iran's oil industry and to expel foreign corporate representatives from the country. After this vote, Britain instigated a worldwide boycott of Iranian oil to pressure Iran economically. Initially, Britain mobilized its military to seize control of the British-built Abadan oil refinery, then the world's largest, but Prime Minister Clement Attlee (in power until 1951) opted instead to tighten the economic boycott while using Iranian agents to undermine Mosaddegh's government. Judging Mosaddegh to be unamenable and fearing the growing influence of the communist Tudeh, UK prime minister Winston Churchill and the Eisenhower administration decided in early 1953 to overthrow Iran's government. The preceding Truman administration had opposed a coup, fearing the precedent that Central Intelligence Agency (CIA) involvement would set, and the U.S. government had been considering unilateral action (without UK support) to assist the Mosaddegh government as late as 1952. British intelligence officials' conclusions and the UK government's solicitations to the US were instrumental in initiating and planning the coup.

The Lord Privy Seal (or, more formally, the Lord Keeper of the Privy Seal) is the fifth of the Great Officers of State in the United Kingdom, ranking beneath the Lord President of the Council and above the Lord Great Chamberlain. Originally, its holder was responsible for the monarch's personal (privy) seal (as opposed to the Great Seal of the Realm, which is in the care of the lord chancellor) until the use of such a seal became obsolete. Though one of the oldest offices in European governments, it has no particular function today because the use of a privy seal has been obsolete for centuries; it may be regarded as a traditional sinecure, but today, the holder of the office is invariably given a seat in the Cabinet of the United Kingdom, and is sometimes referred to as a minister without portfolio.

Since the premiership of Clement Attlee, the position of Lord Privy Seal has frequently been combined with that of leader of the House of Lords or leader of the House of Commons. The office of Lord Privy Seal, unlike those of leader of the Lords or Commons, is eligible for a ministerial salary under the Ministerial and Other Salaries Act 1975. The office does not confer membership of the House of Lords, leading to Ernest Bevin's remark on holding this office that he was "neither a Lord, nor a Privy, nor a Seal".

Clement Attlee was invited by King George VI to form the first Attlee ministry in the United Kingdom on 26 July 1945, succeeding Winston Churchill as prime minister of the United Kingdom. The Labour Party had won a landslide victory at the 1945 general election, and went on to enact policies of what became known as the post-war consensus, including the establishment of the welfare state and the nationalisation of 20 per cent of the entire economy. The government's spell in office was marked by post-war austerity measures; the crushing of pro-independence and communist movements in Malaya; the grant of independence to India, Pakistan, Ceylon, and Burma; the engagement in the Cold War against Soviet Communism; and the creation of the country's National Health Service (NHS).

Attlee went on to win a narrow majority at the 1950 general election, forming the second Attlee ministry. Just twenty months after that election, Attlee called a new election for 25 October 1951, but was narrowly defeated by the Conservative Party, sending Labour into a 13-year spell in opposition.

The National Assistance Act 1948 (11 & 12 Geo. 6. c. 29) is an act of Parliament passed in the United Kingdom by the Labour government of Clement Attlee. It formally abolished the Poor Law system that had existed since the reign of Elizabeth I, and established a social safety net for those who did not pay national insurance contributions (such as the homeless, the physically disabled, and unmarried mothers) and were therefore left uncovered by the National Insurance Act 1946 and the National Insurance (Industrial Injuries) Act 1946. It also provided help to elderly people who required supplementary benefits to make a subsistence living, and obliged local authorities to provide suitable accommodation for those who through infirmity, age, or any other reason were "in need of care and attention not otherwise available to them". The legislation also empowered local authorities to grant financial aid to organizations of volunteers concerned with the provision of recreational facilities or meals.

The National Assistance Board, which administered the National Assistance scheme, operated scale rates which were more generous than in the past. The rate for a married couple before the new service was launched, for instance, was 31 shillings (£1.55) a week, and 40 shillings (£2.00) a week when the new service was introduced, together with an allowance for rent. In addition, as noted by Denis Nowell Pritt, "In most cases where the applicant was a householder, the rent allowance was the actual rent paid."
