Question to the HM Treasury:

To ask the Chancellor of the Exchequer, what estimate he has made of the number of customs declarations that will be required for (a) exports from Great Britain to the EU; and (b) imports from Great Britain to the EU once full border controls have been implemented.

I refer the Rt Hon Member to the answer of 27 July 2021 to UIN 35879 which explains how such an assessment could not be made without disproportionate cost.

The annual figure pertaining to 2021 declarations will be available in due course.
