The merely synthetic construct that is before the House has nothing to do with the real concerns of my right hon. Friend John McDonnell and my hon. Friend Mr Sheerman. It is the dodgy deal—the tuppence-ha’penny Brexit deal—of the Prime Minister. I am led to believe that the Chancellor has ostensibly, but forlornly, attempted to mitigate the Prime Minister’s disastrous handling of Brexit. If that is the case, will he continue his endeavours by using the powers in section 31 of the Taxation (Cross-border Trade) Act 2018 to maintain the UK in a customs union with the EU?
