WASHINGTON The European Union's top trade official said on Wednesday that she is still aiming to complete negotiations for a sweeping free trade deal with the United States this year, despite Britain's vote last week to leave the 28-nation bloc. EU trade Commissioner Cecilia Malmstrom said her team is pressing ahead with talks over the Trans-Atlantic trade and Investment Partnership and is still negotiating on behalf of Britain as a member state, a condition that will continue for perhaps more than two years as London negotiates an exit.
