HISTORIC UK GENERAL ELECTION · 9 JUNE 1983
1983 UK general election results
A 144-seat Conservative majority
Largest party397 seats
The Conservatives dominated the new 650-seat map while the Alliance nearly matched Labour's vote but won only 23 seats.
What happened?
Conservative was the largest grouping with 397 seats, ahead of Labour on 209. 144-seat government majority.
Who formed the government?
Margaret Thatcher led the conservative majority government after the election.
Was it a shock?
The Conservative win was expected. The dramatic story was the electoral system's treatment of the Alliance: almost Labour's vote share, but roughly one ninth of its seats.
CONTEXT
Britain before the vote
The Conservatives had recovered politically after the Falklands War. Labour was divided, and the new SDP-Liberal Alliance challenged the two-party system.
RESULT
What the election changed
The Conservatives won 397 seats, their best total since 1945. Labour fell to 209, while the Alliance took 25.4% of the vote but only 23 seats.
SWING
3.9-point swing to Conservative
Two-party swing from 1979, despite the Conservatives also losing vote share as the Alliance surged.
BOUNDARIES
How to read the seat total
The 1983 election introduced a new 650-seat boundary set used through 1992, making the seat field familiar in scale but not geographically interchangeable with today's map.
