Liberal/SDP (Alliance) - 23 seats with 7.8 million votes
Other - 21 seats with 1.4 million votes
1983 context
Falkland's War victory
Fractioned Labour Party - SDP breakaway
Rising unemployment
Labour's 1983 manifesto (The New Hope for Britain) was too left wing and dubbed the longest suicide note in history. A lot of criticism from members in the party including Tony Blair.
Conservatives wanted to privatise - manifesto was just as radical and ideological but better perceived as Thatcher had control over her party
Alliance wanted to increase the NHS budget, reform the electoral system and advance devolution for Scotland and Wales
Thatcher's campaigning was more presidential, with televised interviews and speeches. She used the media to improve her image whereas newspapers mostly attacked Foot for the inability to manage his party
The voting system penalised Alliance as there was only a difference of 2.2% of the vote share, yet they won 186 fewer seats
There was also evidence of a winners bonus as Conservatives won a landslide victory with only 42.4% of the popular vote
