PARIS, Oct 21 - Britain could still leave the European Union within 10 days time, French Junior Economic Minister Agnes Pannier-Runacher said on Monday. 'One cannot rule out a Brexit within 10 days,' she told Sud-Radio. She said general progress had been made, but added that many small French companies still had to do more work to be ready in the case of a 'no-deal' Brexit. The British government insisted on Sunday the country will leave the European Union on Oct. 31 despite a letter that Prime Minister Boris Johnson was forced by parliament to send to the bloc requesting a Brexit delay.
