United Kingdom general election, 1966

The 1966 United Kingdom general election on 31 March 1966 was won by incumbent Labour Prime Minister Harold Wilson and was regarded as an easy victory.

Wilson's decision to call a snap election turned on the fact that his government, elected a mere 17 months previously in 1964, had an unworkably small majority of only 4 MPs. The Labour government was returned following this snap election with a much larger majority of 96 seats.
