The result was a landslide victory for the Labour Party led by Prime Minister Harold Wilson.

Despite setbacks and a small majority, Labour believed it had an advantage due to the disorientation from the change of leadership at the Conservative Party, the improvement of economic conditions under its brief government, and a victory at the 1966 Kingston upon Hull North by-election.
