Rt Hon David Cameron MP
Prime Minister
10 Downing Street
London

4 September 2012
The Political and Constitutional Reform Select Committee is currently conducting an inquiry into the impact and effectiveness of ministerial reshuffles.
In the light of this week’s reshuffle, I would like to invite you to give oral evidence to the Committee. As the power to appoint, dismiss and move Ministers is a prerogative power of the Prime Minister, you are in a unique position to provide the Committee with an insight into the reshuffle process and the reasons why reshuffles are undertaken.
I would be most grateful for a preliminary written submission to the inquiry.
I have enclosed a copy of the inquiry’s terms of reference for your information.
Yours sincerely
Graham Allen MP
Chair of the Committee
