The Prime Minister held several “hard going” meetings with European Council president Donald Tusk and French president Francois Hollande before leaving at around 5.30am, Brussels time, (4.30am GMT).

He will return to the negotiations later on Friday, Downing Street said, starting with another meeting with Mr Tusk.

Mr Cameron is engaged in a last-ditch bid to secure an EU reform deal which will allow him to call a referendum on British membership on 23 June.

He made no comment as he left following hours of negotiations that also involved the Czech and Belgian prime ministers.

“We have made some progress but a lot still remains to be done,” Mr Tusk said following dinner late on Thursday night.

A Downing Street source said: ”It's hard going. Some signs of progress but nothing yet agreed and still a lot to do.”

Mr Cameron has warned EU leaders that he was ready to walk away from their summit in Brussels without a deal unless they gave ground on key British demands and provided him with a “credible” package he can sell to voters.

Key points of contention are said to be including migrant welfare, child benefit, relations with the Eurozone, treaty change and a British exemption from the requirement for “ever-closer union”.

If a deal is reached, Mr Cameron is expected to hurry back to London for a special Cabinet meeting to endorse the agreement and set a referendum date.
