The British Overseas Territories (BOTs) are fourteen territories that maintain a constitutional or historically recognised connection with the United Kingdom (UK) and constitute part of its sovereign territory, yet lie outside the British Islands. These territories are remnants of the former British Empire which remained under British sovereignty following decolonisation, albeit with varying constitutional statuses.

The permanently inhabited territories exercise varying degrees of internal self-governance, although the UK retains ultimate constitutional oversight, and authority over defence, foreign relations and internal security. While three of the territories are inhabited primarily by military or scientific personnel, the remainder host substantial civilian populations. All fourteen territories recognise the British monarch as head of state and oversight is primarily exercised by the Foreign, Commonwealth and Development Office (FCDO). The total land area of all the BOTs make up 18,015 km (6,956 sq mi), roughly the size of Fiji, which was itself a former British colony.

The World Wide Fund for Nature (WWF) is a Swiss-based international non-governmental organization founded in 1961 that works in the field of wilderness preservation and the reduction of human impact on the environment. It was formerly named the World Wildlife Fund, which remains its official name in Canada and the United States. WWF is the world's largest conservation organization, with over 5 million supporters worldwide, working in more than 100 countries and supporting around 3,000 conservation and environmental projects. It has invested over $1 billion in more than 12,000 conservation initiatives since 1995. WWF is a foundation with 65% of funding from individuals and bequests, 17% from government sources (such as the World Bank, Foreign Office, and USAID) and 8% from corporations in 2020.

WWF aims to "stop the degradation of the planet's natural environment and to build a future in which humans live in harmony with nature." Living Planet Report has been published every two years by WWF since 1998; it is based on a Living Planet Index and ecological footprint calculation. In addition, WWF has launched several notable worldwide campaigns, including Earth Hour and the debt-for-nature swap, and its current work is organized around these six areas: food, climate, freshwater, wildlife, forests, and oceans.

The Colonial Office was a government department of the Kingdom of Great Britain and later of the United Kingdom, first created in 1768 from the Southern Department to deal with colonial affairs in North America (particularly the Thirteen Colonies, as well as the Canadian territories recently won from France), until merged into the new Home Office in 1782. In 1801, colonial affairs were transferred to the War Office in the lead up to the Napoleonic Wars, which became the War and Colonial Office to oversee and protect the colonies of the British Empire. The Colonial Office was re-created as a separate department 1854, under the colonial secretary. It was finally merged into the Commonwealth Office in 1966.

Despite its name, the Colonial Office was responsible for much, but not all, of Britain's Imperial territories; the protectorates fell under the purview of the Foreign Office, and the British Presidencies in India were ruled by the East India Company until 1858, when the India Office was formed to oversee the administration of the new Viceroyalty of India (the Crown ruled India directly through a Viceroy after the Indian Rebellion), while the role of the Colonial Office in the affairs of the Dominions was replaced by the Dominion Office in 1925.

The secretary of state for foreign, commonwealth and development affairs, commonly known as the foreign secretary, is a secretary of state in the Government of the United Kingdom, with responsibility for the Foreign, Commonwealth and Development Office. The role is one of the most senior ministers in the UK Government and is a Great Office of State. The incumbent is a member of the Cabinet of the United Kingdom and National Security Council, and reports directly to the prime minister.

The officeholder works alongside the other Foreign Office ministers. The corresponding shadow minister is the shadow foreign secretary. The Foreign Affairs Select Committee also evaluates the secretary of state's performance.

The Government of the United Kingdom maintains several intelligence agencies that deal with secret intelligence. These agencies are responsible for collecting, analysing and exploiting foreign and domestic intelligence, providing military intelligence, performing espionage and counter-espionage. Their intelligence assessments contribute to the conduct of the foreign relations of the United Kingdom, maintaining the national security of the United Kingdom, military planning, public safety, and law enforcement in the United Kingdom. The four main agencies are the Secret Intelligence Service (SIS or MI6), the Security Service (MI5), the Government Communications Headquarters (GCHQ) and Defence Intelligence (DI). The agencies are organised under three government departments, the Foreign Office, the Home Office and the Ministry of Defence.

Although the history of the organisations dates back to the 19th century or earlier, the British intelligence system as we know it today – with components for domestic, foreign, military, and communications intelligence – did not emerge until the years immediately preceding World War I. The decryption of the Zimmermann Telegram in 1917 was described as the most significant intelligence triumph for Britain during World War I, and one of the earliest occasions on which a piece of signals intelligence influenced world events. During the Second World War and afterwards, many observers regarded Ultra signals intelligence as immensely valuable to the Allies of World War II. In 1962, during the Cuban Missile Crisis, GCHQ interceptions of Soviet ship positions were sent directly to the White House. Intelligence cooperation in the post-war period between the United Kingdom and the United States became the cornerstone of Western intelligence gathering and the "Special Relationship" between the United Kingdom and the United States.
