Question to the HM Treasury:

To ask Mr Chancellor of the Exchequer, what assessment the Government has made of the potential effect on (a) the flow of goods and people at UK ports and (b) the number of additional revenue and customs officials required to carry out customs declarations of the UK leaving the EU customs union.

The Government is committed to securing the most frictionless trading relationship possible with the EU. HMRC is working with other government departments which share the responsibility for maintaining the flow of trade and passengers through our borders.

The resources and staffing levels required by HMRC after the UK leaves the European Union will be dependent on the outcome of negotiations.
