Prime Minister's Question Time, also referred to as PMQs, takes place every Wednesday the House of Commons sits. It gives MPs the chance to put questions to the Prime Minister or a nominated minister. 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. The Leader of the Opposition, Sir Keir Starmer MP, asks six questions and the leader of the second largest opposition party asks two. If a minister takes the place of the Prime Minister, opposition parties will usually nominate a shadow minister to ask the questions.
