John Craik Henderson

Professor John James Craik-Henderson (21 December 1890 – 3 December 1971) was a British Conservative Party politician.

Henderson was elected to the House of Commons at a by-election in March 1940, as Member of Parliament (MP) for Leeds North East.

He served in Parliament for the rest of World War II, and was replaced by the 1945 general election by Alice Bacon of the Labour Party. He took 97.1% of the vote in 1940, opposed only by the British Union of Fascists, but took only 37.5% in 1945. This is one of the biggest drops in British electoral history.
