France warns: 'No-deal' would prevail if UK's Brexit plan still unclear by next week

Britain would only be granted an extension to the article 50 Brexit negotiation period if its parliament passed the current deal on the table or if a clear, alternative plan emerged by next week's EU summit, a French official said on Friday.

"Without clarity - adoption of the Withdrawal Agreement or a clear alternative - a no-deal would prevail," the official at President Emmanuel Macron's office said.

Alternatives would include a second referendum on Britain's divorce from the European Union, a new election, or a change of plan acceptable to both sides such as arrangements already agreed by countries like Canada or Norway, added the official.
