The Prime Minister, David Cameron, answers questions from MPs on subjects that include human trafficking, economic regeneration, defence spending, millennium development goals, funding for voluntary groups and the Building Schools for the Future programme.
Starting at 12 noon, 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, currently Harriet Harman. Normally, she is the only MP allowed to come back with further questions.
