'Cannot rule out Brexit no-deal': France

French Junior European Affairs Minister Amelie de Montchalin says she cannot rule out Brexit talks ending without a deal, while adding it is in Britain's interests to reach a deal.

"I am not ruling out anything," she told Europe 1 radio, when asked on Friday if she could rule out a no-deal Brexit.

"Those who need a deal the most are the British. They cannot withstand a second shock after the epidemic. They wouldn't have access to the security net that is Europe; they wouldn't have access to the stimulus fund," she added, alluding to the economic hit to European states caused by the COVID-19 pandemic.

British Prime Minister Boris Johnson told visiting French President Emmanuel Macron on Thursday that talks on a post-Brexit deal could not drag on into the autumn.

"We will not yield to this deadline pressure, this final sprint that Britain want to impose on us in the hope we will cave in. We do not want a deal for the sake of having a deal but we want a balanced deal," Montchalin said.

Britain left the European Union on January 31 but talks on a future relations had so far made little progress. Johnson and EU leaders say a deal is achievable, but both sides say time is running out and the prospect of no-deal remains.

An internal document obtained by Reuters this week showed the German government was urging other EU states to prepare for a no-deal Brexit, casting doubt on Johnson's public optimism about chances of an early agreement on future ties.

A transition period during which Britain remains in the EU's customs union and single market expires on December 31 and Johnson has ruled out extending it.
