Question to the HM Treasury:

To ask the Chancellor of the Exchequer, if she will make an estimate of the potential economic benefits of entering European Union customs union membership.

No. The Government is working with the EU to identify areas where we can strengthen cooperation for mutual benefit, such as the economy, energy, security and resilience. There will be no return to the customs union. We are committed to finding constructive ways to work together and deliver for the British people.
