In British politics, Blairism is the political ideology of Tony Blair, the former leader of the Labour Party and Prime Minister between 1997 and 2007, and those that support him, known as Blairites. It entered the New Penguin English Dictionary in 2000. Elements of the ideology include investment in public services, expansionary efforts in education to encourage social mobility, and increased actions in terms of mass surveillance alongside a ramping up of law enforcement powers, both of these latter changes advocated in the context of fighting organized crime and terrorism. Blarities have additionally been known for their contrast with the traditional support for socialism by those believing in left-wing politics, with Blair himself and others speaking out against the nationalisation of major industries and against also heavy regulations of business operations.
