We now have the draft deal and a lot of it is stuff we already know. The UK will leave the EU, it will go into a transitional period up till the end of 2020, and it will then go into what's called an all-UK customs arrangement with the EU. To basically mean that there is no hard border across Ireland and no hard border between the UK and the rest of the EU in terms of goods.
There are two things, however, that are going to worry hard Brexiters about that deal. Number one, there's no very clear watertight exit mechanism from the old UK customs arrangement. The UK can't unilaterally leave that arrangement. It needs to make a case to an independent panel of judges. It's not clear how that would go. It's not a firm guarantee it could leave.
And secondly, it looks as though Northern Ireland would remain very firmly and tightly inside both the customs union and the single market under that arrangement, while the UK was outside the single market and also much more loosely related to the customs union. And that is something that's going to really worry, not only hard Brexiters, but of course, the Democratic Unionist party who will fear that a border will go down the Irish Sea. So Mrs May has got a lot that she wanted in that arrangement, but nonetheless, there are things that really will stick pretty badly for those that want to vote her down.
