Deputy Prime Minister, Nick Clegg, answered questions from MPs on subjects including phone hacking, public spending, electoral reform and an independent review of 1994 Mull of Kintyre Chinook helicopter crash.
Starting at 12 noon, the Prime Minister answers questions from MPs in the Commons for half an hour every Wednesday.
In the Prime Minister's absence, the Deputy Prime Minister takes his place.
In most cases, the session starts with a routine ‘open question’ from an MP about the Prime Minister's engagements. MPs can then ask supplementary questions on any subject, often one of current political significance.
Opposition MPs follow up on this or another topic, usually led by the Leader of the Opposition, currently Harriet Harman. Normally, she is the only MP allowed to come back with further questions.
