Talks on a deal between Britain and the European Union on their future relationship face a moment of truth ahead of a meeting of EU leaders next week, European Council President, Charles Michel said.
Michel, speaking in Dublin on Thursday after talks with Irish Prime Minister Micheal Martin, urged Britain to put its cards on the table, saying the bloc needed clarity about their position.
"The coming days are crucial. This is the moment of truth. There is only one week to go before the European Council" meeting on 15-16 October, Michel told journalists.
'A Challenging Situation'
"This is a challenging situation. We think we need more clarity and we will see if it is possible to make real and concrete progress," he said.
The two sides say they are inching towards a deal that would govern around $900 billion in trade after Dec. 31 - when the current transitional arrangements end - though sticking points remain on fishing, level playing field issues and governance.
Martin said the mood around the talks had changed in recent weeks, leading to intensified engagement between the two sides.
"But mood is one thing, it does need substance to follow," Martin said.
The United Kingdom formally left the EU on 31 January, more than three years after it voted 52%-48% for Brexit in a 2016 referendum.
The two sides are now trying to work out how everything from cars to Camembert to whiskey will trade.
