A cabinet minister has resigned after days of mounting pressure over MPs' expenses used on a house in Wimbledon.

Basingstoke MP Maria Miller, a former Merton Conservative, resigned from her role as Secretary of State for Culture, Media and Sport.

She apologised to the House of Commons last week after a parliamentary watchdog told her to pay back interest she saved by using public money to pay for a house in Woodside, Wimbledon, which was designated as her London home.

And as exclusively revealed by our sister newspaper, the Basingstoke Gazette, she apologised to her constituents yesterday and revealed she was "devastated" by the affair.

Prime Minister David Cameron said he was "sad" at the circumstances of her departure and hoped she could make a return "in due course" but was accepting her resignation.

It follows days of mounting public and political pressure on the MP to quit and signs she was losing support among Tory colleagues despite Mr Cameron's backing.

In her resignation letter, Miller told Mr Cameron she was "very grateful" for his personal support.

"But it has become clear to me that the present situation has become a distraction from the vital work this Government is doing to turn our country around," she added.

She defended her work on press regulation - which allies have suggested has resulted in a media "witch hunt" against her.

"Of course, implementing the recommendations made by Lord Justice Leveson on the future of media regulation, following the phone hacking scandals, would always be controversial for the press," she wrote.

"Working together with you, I believe we struck the right balance between protecting the freedom of the press and ensuring fairness, particularly for victims of press intrusion, to have a clear right of redress."

Mr Cameron told her it was " important to be clear that the Committee on Standards cleared you of the unfounded allegations made against you, a point which has been lost in much of the comment in recent days".

The standards committee ordered her to repay £5,800 in overclaimed mortgage interest and say sorry on the floor of the House - an apology which has been widely criticised for its tone and brevity.

"As you leave the Government, you should be proud of your service on the Frontbench and in Opposition," Mr Cameron said - including steering through gay marriage and press regulation.

"I am personally very grateful for the support you have always given me, and which I am sure that you will continue to give.

"I hope that you will be able to return to serving the Government on the Frontbench in due course, and am only sad that you are leaving the Government in these circumstances."
