You can take part in Prime Minister’s questions even if you haven’t been successful in getting a question on the Order Paper. Once an MP with a question on the Order Paper has asked their question and the Prime Minister has replied, the Speaker may call other MPs to ask a supplementary question too. The question doesn’t have to be on the same subject. Stand in your place to indicate that you would like to ask a question. The Speaker will try to call MPs from alternate sides of the House.
