The Brexit negotiators want to reach an agreement on the withdrawal agreement this Sunday. This emerges from an internal document of the EU negotiators, which breaks down the "provisional timetable" and its content was presented to the EU ambassadors on Friday. The paper is available to the Süddeutsche Zeitung.
The hurdles on the way to an agreement are highlighted in red. For this Sunday is noted: "Deal made, nothing made public (in theory)". The agreement will then be approved by the UK Government on Monday. This is followed by a public announcement by British Brexit Minister Dominic Raab and EU Chief Negotiator Michel Barnier in Brussels.
At the center of the negotiations on Saturday, there was still the question of what a backstop could look like if there were no free trade agreement between Brussels and London after the transition phase that runs until the end of 2020.
To avoid a hard border between Ireland and Northern Ireland, a possible compromise solution emerged. Northern Ireland could thus remain in the European internal market for a limited period of time, which would make controls at the inner border superfluous. The rest of the UK could in turn remain linked to the EU in a customs union.
On the other hand, there was resistance from Northern Ireland on Saturday. The Northern Irish party DUP once again rejected any rule that treated Northern Ireland differently than the rest of the kingdom. In order to get a Brexit agreement through the British Parliament, Prime Minister Theresa May needs the support of the DUP.
If there is an agreement this weekend, it should be discussed on the EU side on Tuesday in the General Council and then approved by the 27 Heads of State and Government at their EU summit meeting on Wednesday evening. For the day after it is noted: "Deal with Theresa May confirmed in the European Council".
