The 1957 Wednesbury by-election was held on 28 February 1957 after the incumbent Labour MP, Stanley Evans, resigned from the House of Commons and the Labour Party after he had refused to vote against the Conservative government on the Suez Crisis. The Labour candidate, John Stonehouse, retained the seat with an increased majority.
John Stonehouse won out over the other 28 that were also running in the 1957 election for Labour MP
