The 1929 Wansbeck by-election was a by-election held on 13 February 1929 for the British House of Commons constituency of Wansbeck.
The by-election was triggered by the death of the constituency's Labour Party Member of Parliament (MP) George Warne, who had held the seat since the 1922 general election.
The local Liberal association had selected 39 year-old Harry Anson Briggs as their prospective candidate in 1928.
Briggs had stood for the Liberals in the 1923 general election at Sheffield Attercliffe and in the 1924 general election at Buckrose.
[1] The result was a victory for the Labour candidate George Shield, who held the seat with a greatly increased majority.
