About: United Kingdom general election, 1966

The 1966 UK general election on 31 March 1966 was called by sitting Labour Prime Minister Harold Wilson. Wilson's decision to call an election turned on the fact that his government, elected only two years previously in 1964 had an unworkable small majority of only 4 MPs. Wilson's hope that he would be returned to office with a larger majority had been encouraged by the government's victory in a by-election in Kingston upon Hull North.
