An attempt to avoid a constitutional crisis involving the Welsh, UK and Scottish Governments failed today, though the three sides say they'll keep talking.
They've fallen out over whether Brexit should mean Cardiff Bay and Edinburgh will have to obey Westminster about issues such as food standards and financial support for businesses.
UK ministers made what they called 'a considerable offer' to alter the EU Withdrawal Bill try to end the stalemate in talks with the Welsh and Scottish Governments.
However, it wasn't considerable enough for Finance Secretary Mark Drakeford and Scottish Brexit Minister Mike Russell who left the meeting saying there needed to be more talks.
Today's meeting of the Joint Ministerial Council had been chaired by Theresa May's deputy, David Liddington.
He saw encouraging signs of progress:
Mark Drakeford, who represented the Welsh Government at today's talks, acknowledged that the UK Government had made a concession.
The Welsh and Scottish ministers have called for more talks next week. It's understood that may be difficult because of diary commitments but the UK Government says it will bring forward another meeting.
Welsh Secretary Alun Cairns is upbeat about prospects of agreement.
