Maria Miller has insisted it was her decision to resign as culture secretary amid claims she was forced out by No 10 after a row over her expenses.
In the Commons, Labour leader Ed Miliband accused PM David Cameron of having "undermined trust in politics" with his handling of the row.
The Prime Minister has said that more needed to be done to put parliament's integrity "beyond doubt".
