UK’s Withdrawal from the EU

I thank the right hon. and learned Gentleman for giving way because I actually find that I agree with a great deal of what he is saying. He is saying that leaving with no deal would bring huge consequences for our economy and we should not countenance it. He is also saying that within the withdrawal agreement he sees the need for a backstop. I have listened closely to what he said before: that he also agrees on the elements about needing a transition period and certainty on citizens’ rights. Given that he now appears to agree with everything that is in the withdrawal agreement, why will he not vote for it and what more does he need?
