Christine Lagarde, the French finance minister, and Chancellor George Osborne are expected to talk in the coming days in a final attempt to reach an agreement on controls for hedge funds and private equity firms before a gathering of finance ministers early next week.
The Belgian presidency of the council this week released yet another compromise draft of the directive, further refining its previous proposals for a passport to market non-EU funds to EU investors.
The UK – along with Sweden, the Netherlands and the Czech Republic – is reluctant to sign up to this latest draft.
Belgium also proposed giving new powers to the European Securities and Markets Authority, a new EU watchdog, which Paris wants to take over the running of the passport scheme which France opposes.
The controversial legislation has caused rifts since it was first proposed in April 2009. It has also antagonised Washington, which believes the French plans are protectionist. US Treasury Secretary Timothy Geithner has written to Ms Lagarde warning her against trying to control the operations of foreign hedge funds.
