Ministers are responsible for the speed and content of their answers. If you receive an answer that is late, inaccurate, incomplete or unsatisfactory, you should discuss your concerns with the Table Office. They can advise you on taking further action.
For answers that are very late, you can ask a ‘chasing’ question (in the form “when s/he plans to answer Question 123456, tabled by the hon. Member for [Constituency] on [Date Month Year]”).
If an answer gives rise to further questions, you can ask a ‘pursuant’ question requesting more information (in the form “Pursuant to the Answer of [Date Month Year] to Question 123456 on [Title of Question], …”).
