Prime Minister's Questions
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, Edward Miliband. Normally, he is the only MP allowed to come back with further questions.
