Paris (AFP) - More negotiations are required before Britain's EU partners can agree to a deal to try to prevent it leaving the bloc, a French official said Monday.

Speaking after Prime Minister David Cameron held talks in Paris with President Francois Hollande, the official said although there was a "political willingness" to find an agreement, "more work is needed, particularly on economic governance".

Britain, which does not use the euro, wants a deal that will protect it from ever having to pay into a fund to protect the eurozone.

It also wants any issues that affect all member states to be discussed by all 28 member states and not just the 19 nations that use the euro.

Cameron hopes to secure a deal at an EU summit this Thursday and Friday, which could pave the way for an "in-out" referendum to be held in Britain by June.
