Theresa May 'extremely sorry' over Harper resignation

Mark has been an excellent minister and he can be proud of the role he has played in sharply reducing immigration to Britain.

He has been a first-rate colleague and his decision reflects his loyal commitment to the Conservative Party, the Government and the Prime Minister.

I am extremely sorry to lose him from the Home Office but I am confident that he will be able to bring his considerable talents to government as a minister again in future.
