2/ The title is interesting - it is: "How we will deliver the best Brexit in 2018". Davis's piece does not come close to answering that. The piece would more accurately be entitled "What I think the best Brexit looks like in 2018 (without asking the EU what they'd accept)"
3/ There's a bit of nerdy stuff at the start. I quote: "Donald Tusk has approved an immediate start to initial discussions on the future relationship (...) talks about the implementation period begin early in the New Year" I assume he means "Transition Period"?
