The hon. Gentleman is right that all the manifestos referred to honouring Brexit by leaving the customs union and the single market. Labour put it in a slightly more nuanced way but, particularly in leave areas, people were told that we would be leaving the single market and the customs union.
This will be very important vote. As we have heard, it is absolutely crucial that we do not allow Lords amendment 19 to be carried. Today we must make a decision. We either support those 17.5 million people who voted to leave, or we say that we will allow people who really want to stop Brexit—by using procedural mechanisms, legal challenges and legal words—to put the whole thing in doubt. I am confident that, in the end, we will not allow the Lords—the unelected House of Lords, which is full of former EU commissioners and people who are funded by the European Union—to decide what we are going to do.
