It seems to be quibble whether putting forward something that you know, without any input from the EU does not meet what you agreed to in December. I think that is not a genuine proposal, but if you want to say it is, who cares? It does not change that the proposal the UK will put forward will be after the Brussels meeting, not before it.

Believe it or not, the EUs primary interest is what it thinks is in the best long term interest of the EU, including trade and social and political aspects. Suggesting it is only doing so to pressurise the UK is real "Fog in the channel, continent cut off" thinking.
