The Times reported (paywall) this morning that:
Negotiations on Britain’s future trade agreement will continue only if last week’s withdrawal deal is quickly turned into a legally binding treaty, European Union leaders will state.
A text to be agreed by them this week calls on Theresa May to “start drafting the relevant parts of the withdrawal agreement” into law.
In language aimed at David Davis, the Brexit secretary, they will warn that any attempt to backtrack on last Friday’s agreement would result in the EU halting trade talks.
EU officials and diplomats were irritated by Mr Davis’s remark at the weekend that the withdrawal agreement was just a “statement of intent”. “It’s not helpful if people cast everything into doubt 24 hours later,” one source said.
And why not?
First, there is the perfidious Mr Davis to consider.
Second, there is the fact that no British parliament can bind another, but a Treaty can, and that matters when commitments for up to eight years are being made to secure a deal for EU citizens which are otherwise worthless.
And if I was the EU, and Ireland, I'd be saying put that in both law and a Treaty or forget moving on.
To put it another way, it's time to stop kicking this issue into touch and for a decision to be made. I sincerely hope that in the light of UK comments since Friday that now happens.
