I am grateful to the right hon. Member for giving me notice of his point of order. The Table Office will be able to advise him about the tabling of questions. The Government decide which Department responds. The Table Office will be able to advise about the most appropriate Department to direct the questions towards in the first instance. The normal rules about questions, including on ministerial responsibility, would of course apply.
Select Committees may seek evidence from a wide range of sources and certain options are open to them if that evidence is not provided.
