MP wants nine Whitehall departments merged or closed
17 June 2013 Last updated at 15:00 BST
The present 20 government departments should be almost halved with some merged or abolished, saving £8bn a year and cutting bureaucracy and waste.
Conservative MP Dominic Raab said his plans for 11 larger departments would not hit front line services, and could lead to "more joined-up policy making".
Next week, the chancellor will announce the result of his Spending Review where departments will find out how much they will have to spend in the years ahead.
