I think it is access to the single market, and we are both aware of the difference between those two things. Also, it is “a” customs union; I noticed that the noble Lord referred to “the” customs union. That is also something different, so his view is not quite that.
There is a second question: whether if the Labour Party decides it is going to move to this position—either as a snail or a crab; those were the noble Lord’s chosen animals—that it would then support the withdrawal agreement, which would be needed in order to pave the way for this. If it is not going to, that is significantly less attractive to someone like me looking to ensure that we do not leave without a deal. These questions are not put as a challenge—they are a genuine dilemma for those of us who are now looking at what the solutions are, who are not persuaded after the Brady amendment that we are going to get very big changes from the European Union, and who want to be sure that we can all agree on something.
