As Theresa May and Brexit Secretary David Davis arrived in Brussels this morning, expectations were high that she was there to sign off on the first phase of the Brexit negotiations. By the time she left just a couple of hours ago, it was clear that there is much more to do. The sticking point again is the Irish border. Theresa May cannot proceed without the agreement of the Democratic Unionist Party, and at the last minute they objected to talk of regulatory alignment between the Republic of Ireland and Northern Ireland. The Taoiseach Leo Varadkar said he was disappointed, but in Brussels they’re still saying a deal is within reach.
