THERE is still a "huge uncertainty" over the UK's Brexit position, First Minister Carwyn Jones said after meeting with Prime Minister Teresa May today.

Speaking after the Downing Street summit was held this afternoon - attended by Mr Jones, his Scottish counterpart Nicola Sturgeon and First Minister and Deputy First Minister of Northern Ireland, Arlene Foster and Martin McGuinness.

Labour's Carwyn Jones said there had been no details about what happens next in the divorce talks, and warned "time is not on our side".

The Welsh First Minister said access to the single market was the most important issue, but dismissed suggestions by Nicola Sturgeon that Scotland could remain part of the trading agreement even if the rest of the UK did not.

“There is still huge uncertainty about what success will look like from the UK Government. That makes it difficult for the devolved administrations to positively influence the process, but we are still committed to working for the best deal for Wales," he said.

“I argued very strongly for full and unfettered access to the single market – my key priority remains the Welsh economy and securing more and better jobs for Wales. For us, that must be the starting point for negotiations.

“I welcome the fact the UK Government has conceded to the demands of the devolved administrations to meet more frequently, and for us to have a meaningful role in developing the future work programme relating to Brexit.”

Mrs May said: "Working together, the nations of the United Kingdom will make a success of leaving the European Union - and we will further strengthen our own unique and enduring union as we do so.

"The great union between us has been the cornerstone of our prosperity in the past - and it is absolutely vital to our success in the future.

"The country is facing a negotiation of tremendous importance and it is imperative that the devolved administrations play their part in making it work.

"We have important work to do for the UK in terms of negotiating a smooth exit from the EU and getting the best possible deal for the whole of the UK."
