Wednesday at 3.15 pm, immediately after Ministerial
Questions. Like these, there are strict rules about the
way in which questions can be posed - and MPs have
learnt to use ingenious formulae to get round these rules.
In the past, for instance, Prime Ministers tended to
transfer questions which dealt with matters under control of
a government department to the minister responsible. However,
MPs are allowed to ask a supplementary question which the Prime Minister does not see in advance. This led to the development of the 'transfer-proof' question, the most famous of which is where the MP first asks the Prime Minister to list his engagements for the day - and then follows through with an unseen supplementary, which can raise any issue the MP chooses.
