The hon. Gentleman is absolutely right that there are concerns about issues such as security. That is the very essence of why we need the deal. It will provide confidence on issues such as security and it will secure the implementation period so that things such as security measures will remain in place.
It was clear in the debate before Christmas that there were many views in the House about what trade deal we should enter into with the EU. The possible trade deals included no deal, no deal plus, Norway, Norway plus, Canada, Canada plus, Norway for now and Norway forever. There is a whole spectrum of deals that different Members cling to, but the reality is that whatever deal is to be put in place, it requires the winding down of our 45-year relationship with the European Union. Therefore, whatever deal is put in place requires a withdrawal agreement, and that withdrawal agreement requires a backstop.
