It now becomes a question of whether Angela Merkel and other key leaders are prepared to throw Ireland under a bus and agree to drop the "Irish Backstop" from the Withdrawal agreement in order to facilitate "an orderly Brexit", or will they maintain solidarity with the member state most effected by Brexit?

There's nothing much the EU can do to protect Ireland from  Brexiteers who is willing to go for no deal if the alternative is the backstop.

So the question is whether the EU decides to let no deal happen in solidarity with Ireland or it negotiates a deal with a British PM whose red lines include breaking the single market on the island of Ireland.
