David Cameron's and European Council President Donald Tusk's officials are set for a "crucial" day of talks about the UK's renegotiated membership of the EU.
A meeting between the two laeders on Sunday night ended without a deal, though a Downing Street source said there had been a "breakthrough" on restricting benefits for EU migrants.
Mr Tusk said "intensive work" would be needed during the coming hours.
The aim is to agree a deal to be put to EU leaders ahead of a summit on 18 and 19 February.
