Britain's vote to quit the EU won't affect negotiations to hammer out a EU-US trade deal aimed at creating the world's largest free trade and investment area, the EU's top trade official said Thursday.

"We are determined to continue these negotiations. They are important for Europe, for our economy, for our jobs, for our business people, for our consumers, and it makes a lot of sense to do it even with 27," EU trade commissioner Cecilia Malmstroem said on French radio.
