Urgent questions are taken immediately after Question Time and before any oral statements, except on Fridays when they are taken at 11am. The Government decide which minister will respond to your urgent question.
When the Speaker calls your name, you read out your urgent question and the minister answers (for up to three minutes). You can then make a brief response (for up to two minutes). The minister replies. The official Opposition spokesperson may speak for up to two minutes, and the third party spokesperson for up to one minute.
The Speaker then allows other MPs to ask supplementary questions, usually for about half an hour, taking into account the number of MPs and the other business for the day. If you want to be called, you must be in the Chamber for the start of the urgent question.
