Created in 2001, the Department for Work and Pensions (DWP) is the largest government department. It was formed from the merger of the Department for Education and Employment and the Department of Social Security. Head of the department is the Secretary of State for Work and Pensions in the Cabinet. DWP’s budget for the year 2011 to 2012 was £151.6 billion; about 28 per cent of the UK government’s spending. As a result the department spends a larger share of the UK national wealth than any other department.
