Deputy Prime Minister, Nick Clegg, answered questions from MPs on behalf of the Prime Minister, David Cameron, on subjects such as tuition fees, contaminated blood, elections in Burma and the Port of Dover. The Deputy Leader of the Labour Party, Harriet Harman, asked questions on behalf of the Leader of the Opposition, Ed Miliband.
Starting at 12pm, the Prime Minister answers questions from MPs in the Commons for half an hour every Wednesday.
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, Ed Miliband. Normally, he is the only MP allowed to come back with further questions.
