I thank the hon. Gentleman for his call for sensible and respectful debate and agree with him that every effort needs to be made to preserve our precious Union. One thing that is very clear in this House, notwithstanding all the differences that we have, is that we will not allow any proposals from the EU to draw a customs line down the Irish sea.
The hon. Gentleman asked about Northern Ireland and our proposals. Our White Paper proposals on the economic partnership will provide the long-term sustainable answer to this question. As well as preserving frictionless trade with our EU partners, they will, in the process, resolve the concerns around the Northern Irish border. At the same time, we remain committed to the joint report in December, which would be for a limited, finite and temporary backstop.
The hon. Gentleman also asked about economic analysis. That will be made available in time for the meaningful vote. Finally, he asked about staying in the single market and the customs union. The reality is, as he well knows, that if we stay members of the single market and the customs union, we would not be leaving the EU.
