The exact terms of what makes up Thatcherism, as well as its specific legacy in British history over the past decades, are controversial. Ideologically, Thatcherism has been described by Nigel Lawson, Thatcher's Chancellor of the Exchequer from 1983 to 1989, as a political platform emphasising free markets with restrained government spending and tax cuts, coupled with British nationalism both at home and abroad. Although Thatcher herself rarely used the word "Thatcherism", during her campaign for the 1987 general election she gave a speech in Solihull and when describing the economic successes there she said, "That's what I call Thatcherism".
