If a majority decision is reached by MPs today it will be for a soft Brexit. They will vote for a customs union with the EU or even to remain in the single market. As this is not, in the slightest, what leavers voted for in the referendum, the government should just go ahead and cancel Brexit. This is what most MPs want to do but are too scared to do because many might lose their seats were they to blatantly ignore the wishes of their constituents. However, a soft Brexit would be the worst of all worlds and please no one. It would not be in the UK's interest whatever you might think its interests actually are. Above all, it would be boring. Brexit would end, not with a bang but a whimper.
