France's Loiseau says there has been no discussion between Macron and May on extending Article 50

France's minister for European affairs, Nathalie Loiseau, comments

• No one wants to trap UK inside backstop
• Regarding assurances, says that "there is nothing more we can do"

She's mainly referring to discussions that were had between May and Macron during the Christmas holiday. As for a summary of the current situation, that last comment sums it up pretty well. If not, you can also adopt ERG vice-chair Mark Francois' commentary:

"Putting some love letter on top of it (the Withdrawal Agreement) has no legally binding effect at all"
