Leader of the Liberal Democrats in the context of "Liberal Democrat Conference"

Charles Peter Kennedy (25 November 1959 – 1 June 2015) was a British politician who served as Leader of the Liberal Democrats from 1999 to 2006, and was the Member of Parliament (MP) for Ross, Skye and Lochaber from 1983 to 2015.

Kennedy was elected to the House of Commons in 1983 as a member of the Social Democratic Party, and after the SDP–Liberal Alliance merged into the Liberal Democrats, became the party's president. Following the resignation of Paddy Ashdown in August 1999, Kennedy became the party's leader. He led the party in the 2001 and 2005 general elections, increasing its number of seats in the House of Commons to their highest level since 1923, led his party's opposition to the Iraq War, and broadly positioned the party to the left of New Labour. A charismatic and affable speaker in public, he appeared extensively on television during his leadership.

The Liberal Democrats are a political party in the United Kingdom. While in opposition, the Leader of the Liberal Democrats appoints a frontbench team of members of Parliament (MPs), peers in the House of Lords, members of the Scottish Parliament (MSPs), and members of the Senedd (MSs) to speak for the party on different issues. Their areas of responsibility broadly corresponded to those of Government ministers. The frontbench team is divided into departmental sub-units, the principal ones being the economy, foreign policy, and home affairs. Sometimes the frontbench team consists of more than just the principal positions.
