Local elections were held in the United Kingdom in 1991. The results were a setback for the governing Conservative Party, who were left with their lowest number of councillors since 1973 - though their popular vote was an improvement from the 1990 local elections (John Major had succeeded Margaret Thatcher as prime minister in November 1990), and the Conservatives would go on to win the general election in 1992. Labour and the Liberal Democrats both benefited from the Conservative losses.
