@MichelBarnier , @WeyandSabine , and everyone else involved, including on the UK side, deserves huge credit for getting the process to this stage: many congratulations. Given how many red lines had to be navigated it is a massive achievement.
Attention in the UK will focus on the imperfections of the deal but those are merely the reflection of the political red lines - leave the EU, leave the SM, no customs border between NI and GB - that negotiators had to work with.
What Barnier and colleagues have achieved is to construct a pathway towards an orderly Brexit, something that has not always seemed likely. And if a future HMG changes their red lines, the future relationship could be very close indeed.
