Margaret Thatcher was a prime minister.
Thatcher was criticised for the neglect of the Falklands' defence that led to the war, and especially by Labour MP Tam Dalyell in Parliament for the decision to torpedo the General Belgrano, but overall she was considered a competent and committed war leader
Thatcher was replaced as head of government and party leader by Chancellor John Major, whose lead over Heseltine in the second ballot was sufficient for Heseltine to drop out
