That would be to repeat the mistake of Article 50, which a lot of remain MPs endorsed in the wake of the 2016 referendum. They feared being on the wrong side of majority opinion. Instead, they put themselves on the wrong side of history.
Wrong doesn’t become right simply because it has a majority in the House of Commons, least of all when parties supporting a second referendum outpolled the parties against on 12 December.
And that was with Jeremy Corbyn leading the Labour Party. Polls showed consistently that voters were against both Brexit and Corbyn, but they hated Corbyn more than Brexit.
