The Latest on talks on a deal for Britain at the European Union summit (all times local):

10:40 a.m.

French President Francois Hollande is insisting that new European Union rules for Britain should maintain strict financial regulation.

France is putting up tougher-than-expected resistance to British Prime Minister David Cameron's push for EU reform ahead of a British referendum on whether to stay in the 28-nation union.

Arriving for the second and final day of an EU summit in Brussels on Friday, Hollande said there is still work to be done before reaching a deal with Britain despite talks that stretched nearly until dawn.

He insisted that Britain should not be given any "right of veto or blockage" and that all EU countries should have rules limiting speculation and avoiding new financial crises.

Countries like France that share the euro currency worry that protections for Britain and other non-eurozone nations would offer unfair advantage to Britain's financial center, the City of London.

British Prime Minister David Cameron faces tough new talks with European partners after through-the-night meetings failed to make much progress on his demands for a less intrusive European Union.

Britain's future in the union — along with heightened tensions around Europe's migrant crisis — are dominating an EU summit in Brussels scheduled to finish Friday with what Cameron hopes is a deal for EU reform.

He wrapped up talks in Brussels around 5:30 a.m. and is expected to resume meetings late morning.

A British official speaking on customary condition of anonymity said Friday morning there are "some signs of progress but nothing yet agreed and still a lot to do."

Cameron wants a deal that will let him urge Britons to vote "yes" to continued membership in an upcoming referendum.
