Question to the HM Treasury:

To ask Mr Chancellor of the Exchequer, what assessment his Department has made of the effect on the UK economy of the UK leaving the EU's Common Commercial Policy and Common External Tariff without a customs agreement between the UK and the EU.

The government has undertaken a significant amount of work to assess the economic impact of leaving the EU. This is part of our continued programme of rigorous and extensive analytical work on a range of scenarios on a sector by sector basis.

We want to conclude a deep and special partnership with the European Union. This includes pursuing a new customs agreement that allows for the freest possible trade in goods and services between the UK and EU member states.
