GENEVA (Reuters) - France warned on Monday that European Union governments might not give unanimous approval to a final global trade deal if it was based on compromise proposals being discussed at the World Trade Organization.

"The risk exists that on this current basis there might not be unanimity in the European council of ministers next year on a final agreement," French Agriculture Minister Michel Barnier told Reuters in an interview.

Asked whether France would use its power of veto to block a final deal, Barnier said: "I did not use that word."
