Social Democratic Party (UK) in the context of "Charles Kennedy"

The Liberal Democrats, colloquially known as the Lib Dems, is one of the major political parties in the United Kingdom. Ideologically adhering to liberalism, it was founded in 1988. The party is based at Liberal Democrat Headquarters, which since September 2025 has been based at Buckingham Gate, in the Westminster area of Central London. The party's leader is Ed Davey. It is the third-largest party in the United Kingdom, with 72 members of Parliament (MPs) in the House of Commons. It has 75 members of the House of Lords, 5 in the Scottish Parliament, 1 in the Welsh Senedd, and around 3,200 local council seats. The party holds a twice yearly Liberal Democrat Conference, at which policy is formulated. In contrast to its main opponents, the Lib Dems grant all members attending Conference the right to vote on policy, under a one member, one vote system. As well as voting in the Conference Hall, the party allows its members to vote online for its policies and leadership elections. Members are also free to join organisations representing strands of party thinking, such as Liberal Reform and Social Liberal Forum, and for those under 30 years, Young Liberals.

In 1981, an electoral alliance was established between the Liberal Party, a group which descended from the 18th-century Whigs, and the Social Democratic Party (SDP), a splinter group from the Labour Party. In 1988, the parties merged as the Social and Liberal Democrats, adopting their present name a year later. Under the leaderships of Paddy Ashdown and Charles Kennedy, the party grew in the 1990s and 2000s, focusing its campaigns on specific seats and retained the third-largest party status in the House of Commons, although with significantly more seats than the predecessor Liberal Party. In the 1997 election, the Liberal Democrats doubled their seat count to 46. In 2010, under Nick Clegg's leadership, the Lib Dems were junior partners in the Conservative-led coalition government, in which Clegg served as deputy prime minister. Though it allowed the party to implement some of its policies, the coalition damaged its electoral standing; it lost 48 of its 56 MPs at the 2015 general election, which relegated it to fourth-largest party in the House of Commons. Under the leaderships of Tim Farron, Vince Cable and Jo Swinson, the party refocused as a pro-Europeanist party opposing Brexit. In the 2019 general election, the party garnered 11.5% of the vote on an anti-Brexit platform, but this did not translate into seat gains. However, the party's success was renewed under the leadership of Ed Davey, winning hundreds of councillors and 72 MPs in the 2024 general election, its highest result since 1923, and resuming its status as the third largest party in the House of Commons.

The Liberal Party was formally established in 1859 and existed until merging with the Social Democratic Party in 1988 to create the Liberal Democrats.

In the United Kingdom, the word liberalism can have any of several meanings. Scholars primarily use the term to refer to classical liberalism. The term can also mean economic liberalism, social liberalism or political liberalism. It can simply refer to the ideology and practises of the historic Liberal Party (1859–1988), or in the contemporary context, of the Liberal Democrats: the successor to the old Liberal Party after it merged with the centrist Social Democratic Party (SDP), with which the Liberals had been in a Britain-wide electoral alliance since shortly after the latter was formed.

Liberalism can occasionally have the imported American meaning, especially since 2016; however, the pejorative connotation is much weaker in the UK than in the US, and social liberals from both the left and right wing continue to use liberal and illiberal to describe themselves and their opponents, respectively.

The SDP–Liberal Alliance was a centrist and social liberal political and electoral alliance in the United Kingdom.

Formed by the Social Democratic Party (SDP) and the Liberal Party, the SDP–Liberal Alliance was established in 1981, contesting the 1982 United Kingdom local elections, 1983 United Kingdom local elections, 1983 general election, 1984 United Kingdom local elections, 1984 European election, 1985 United Kingdom local elections, 1986 United Kingdom local elections, 1987 United Kingdom local elections and 1987 general election.

Roy Harris Jenkins, Baron Jenkins of Hillhead (11 November 1920 – 5 January 2003) was a British politician and writer who served as President of the European Commission from 1977 to 1981. At various times a Member of Parliament (MP) for the Labour Party and the Social Democratic Party (SDP), and a peer for the Liberal Democrats, he was Chancellor of the Exchequer and Home Secretary under the Wilson and Callaghan Governments.

The son of Arthur Jenkins, a coal-miner and Labour MP, Jenkins was educated at the University of Oxford and served as an intelligence officer during the Second World War. Initially elected as MP for Southwark Central in 1948, he moved to become MP for Birmingham Stechford in 1950. On the election of Harold Wilson after the 1964 election, Jenkins was appointed Minister of Aviation. A year later, he was promoted to the Cabinet to become Home Secretary. In this role, Jenkins embarked on a major reform programme; he sought to build what he described as "a civilised society", overseeing measures such as the effective abolition in Britain of both capital punishment and theatre censorship, the partial decriminalisation of homosexuality, relaxing of divorce law, suspension of birching and the liberalisation of abortion law.
