The Silvertown by-election of 1940 was a wartime by-election.
Silvertown was a safe Labour seat, and none of the major parties stood against the Labour candidate."Labour Victory At Silvertown", The Times, 24 February 1940, p. 6.
It was one of the last by-elections contested by the British Union of Fascists which campaigned on a platform calling for an immediate peace with Nazi Germany, a policy which won them only 151 votes.Robert Benewick, Political Violence and Public Order, p. 291-2
