As Roly pointed out last week, we certainly live in interesting times.
Labour has no issue with the Withdrawal Agreement (insofar as it is possible to tell), but voted against it when it was put forward on a standalone basis last Friday.
MPs essentially falling out over the Political Declaration, even though its contents can bind neither the EU nor the government.
Parliament moving towards incorporating a commitment to a Customs Union arrangement into the (non binding) Political Declaration with no idea of the 'price' that the EU will demand for it.
Utterly bonkers.
