From the Guardian, 4th December:

====
May had been given the deadline of Monday 4 December to table the offers before a European council summit on 14 December, when EU leaders will decide if "sufficient progress" has been made to proceed to the next phase.


But although the money and citizens' rights issues have been mostly resolved, the future arrangement with Ireland has remained a significant obstacle because the British government has yet to offer a firm commitment explaining how it will guarantee avoiding a return to a hard border after Brexit.
[...]
Chances of a deal with British officials had been put at 50:50 on Sunday afternoon, but at midnight Brussels time, officials said an agreement had not been reached.

I haven't seen a reference anywhere else to the midnight statement. Of course, we may still be playing brinkmanship.
