The First Female British Prime Minister

The Labour government then faced fresh public unease about the direction of the country and a damaging series of strikes during the winter of 1978–79, dubbed the "Winter of Discontent". The Conservatives attacked the Labour government's unemployment record, using advertising with the slogan "Labour Isn't Working". A general election was called after the Callaghan ministry lost a motion of no confidence in early 1979. The Conservatives won a 44-seat majority in the House of Commons and Thatcher became the first female British prime minister.
