Jacob Rees Mogg in the FT today is saying that he no longer wants the backstop to be scrapped as a condition for supporting May's deal. Which seems like a very significant concession.
If Rees Mogg really said that then one must wonder why. Staying stuck in the EU with no legal way to extract oneself is the antithesis of exiting the EU. Maybe he's trying to guarentee that the deal is rejected a second time.
He says he wants to pursue other legal mechanisms to make it non-permanent but hasn't said anything about what those are or how he wants them achieved. It looks very much like he is giving in. Whether the rest of the ERG follows is of course another question.
//Mr Rees-Mogg, told the Financial Times that he was no longer insisting that the contentious “Irish backstop” be scrapped as a condition for his support for Mrs May’s deal and was prepared to consider other legal fixes to ensure it did not become permanent.//
