HMRC Closures

My hon. Friend makes his point, as always, very eloquently. He mentioned Brexit, and another angle of that is that many of the HMRC proposals were decided before the European Union referendum. Does he agree that once the Brexit negotiations reach a settlement—if we ever get one—that will inevitably cause issues for HMRC, not least the customs union and related areas? Is that not enough to put the HMRC proposals on pause at least until we get to that stage?
