Britain must "translate speeches into treaties" and come up with a detailed plan for its post-Brexit ties with the EU, European Commission President Jean-Claude Juncker said yesterday.
EU leaders have been pressing British Prime Minister Theresa May to clarify what she wants before they agree their position on the future economic partnership at a summit later this month.
A series of speeches by May and her senior ministers have done little to satisfy Brussels, and Juncker warned it was particularly crucial for London to clarify its plans for the sensitive issue of the Irish border.
"As the clock counts down with one year to go, it is now time to translate speeches into treaties, to turn commitments into agreements, broad suggestions and wishes on the future relationship into specific workable solutions," Juncker told the European Parliament in Strasbourg.
He said it was "especially important" that Britain comes up with concrete proposals for the border between British-ruled Northern Ireland and the Republic of Ireland, which is staying in the EU.
Both Britain and the EU have vowed to avoid the return of customs checks to the border.
