United Kingdom general election, 1955 The 1955 United Kingdom general election was held on 26 May 1955, four years after the previous general election. It resulted in a substantially increased majority of 60 for the Conservative government under new leader and prime minister Sir Anthony Eden against the Labour Party, then in their twentieth year of leadership by Clement Attlee.
United Kingdom general election, 1847 The 1847 United Kingdom general election saw candidates calling themselves Conservatives win the most seats, in part because they won a number of uncontested seats. However, the split among the Conservatives between the majority of Protectionists, led by Lord Stanley, and the minority of free traders, known also as the Peelites, led by former prime minister Sir Robert Peel, left the Whigs, led by Prime Minister Lord John Russell, in a position to continue in government.
