John Smith, Scottish-English lawyer and politician, Shadow Chancellor of the Exchequer (b. 1938)
John Smith (13 September 1938 – 12 May 1994) was a Scottish Labour politician who served as Leader of the Opposition and Leader of the Labour Party from July 1992 until his death from a heart attack in May 1994.

Smith first entered Parliament in 1970 and, following junior ministerial roles as Minister of State for Energy (1975–1976) and Minister of State for the Privy Council Office (1976–1978), he entered the Cabinet towards the end of James Callaghan's tenure as Prime Minister, serving as Secretary of State for Trade and President of the Board of Trade (1978–1979). During Labour's time in Opposition to Margaret Thatcher's Conservative government, he rose through the Shadow Cabinet, serving as Shadow Secretary of State for Trade (1979–1982), Shadow Secretary of State for Energy (1982–1983), Shadow Secretary of State for Employment (1983–1984), Shadow Secretary of State for Trade and Industry (1984–1987) and Shadow Chancellor of the Exchequer (1987–1992).

After Labour leader Neil Kinnock resigned following the Party's surprise loss in the 1992 general election to new Conservative leader John Major, Smith was elected his successor in July 1992. He continued Kinnock's moves to reform Labour, abolishing the trade union block vote at Labour party conferences and replacing it with "one member, one vote" at the 1993 party conference. However, his overall cautious approach to reform, which was dubbed "one more heave", sought to avoid controversy and win the next election by capitalising on the unpopularity of the Conservative government. This frustrated figures on the Labour right, such as Tony Blair and Gordon Brown. Following Smith's sudden death in 1994, he was succeeded as Leader by Blair, who became prime minister three years later.
