Question to the HM Treasury:

To ask Mr Chancellor of the Exchequer, what estimate he has made of the additional cost to (a) business and (b) the Government of the (i) maximum facilitation and (ii) customs partnership proposals for the UK's future customs arrangements with the EU.

The government is considering two approaches to a future customs relationship with the EU: a ‘new customs partnership’ and a ‘highly streamlined customs arrangement.’ Ongoing analysis continues to support the development of both models.

Current assessment of the ongoing costs under the two models was published in a letter by the Chief Executive of Her Majesty’s Revenue and Customs to the Treasury Select Committee on 5 June, 2018.
