The BBC's Brussels reporter Adam Fleming says it is EU policy not to get involved in the proceedings happening in the UK at the moment.
He says Chancellor Merkel has said she thinks the deal on the table "cannot be reopened", which has been echoed by senior officials in Brussels.
Adam Fleming suggests many officials in Brussels believe the EU has already "bent over backwards".
He says negotiations on the text of the agreement are still going in Brussels, and if the UK government remains so fragmented, EU officials could make more tweaks to the text before it is published.
