Dr Julian Lewis: The Prime Minister’s mention of the World Trade Organisation reminds me that the Chancellor, in his Budget, wisely allocated £3 billion to £4 billion for practical preparations for exiting the EU on a WTO basis. Has each Government Department now received its allocated share of those funds? If not, why are they being held back?

[The Prime Minister: The funds are not being held back, and Government Departments will receive notification of the allocation of the funds in the next few days.]
