James Callaghan (1912–2005) was a Labour politician who held all four of the ‘great offices of state’ —Chancellor of the Exchequer, Home Secretary, Foreign Secretary, and Prime Minister.
As Home Secretary from 1967 to 1970, Callaghan oversaw the Metropolitan Police’s Special Branch, including the Special Demonstration Squad (SDS) in 1968.
Callaghan became Prime Minister in 1976. The Grunwick strike of 1976–78, led mainly by Asian and female workers demanding union recognition, tested his government’s relationship with the trade union movement.
Though publicly sympathetic to collective bargaining, Callaghan refused to intervene decisively in support of the strikers, wary of alienating employers and right-wing opinion. His caution alienated sections of the labour movement and exposed the gap between Labour’s rhetoric of solidarity and its actions in practice.
