Theresa May and Brexit in Swansea

Unless the Tory government took that debate seriously it risked fracturing the country, Mr Jones said.

Ms Sturgeon said at the weekend that she was prepared to be flexible on her deadline for a second Scottish referendum, indicating that 2019 could be an acceptable target for the plebiscite: "If she (Mrs May) is talking in the spring of 2019, a bit later perhaps than I was suggesting, there may be some room for discussion around that". We're not a region, thanks.

Her trip comes as the government is resisting calls from Nicola Sturgeon, Scotland's first minister, to hold a second referendum on Scottish independence before Brexit is complete.

His comments were also supported by former prime minister Gordon Brown, who said a new form of federal home rule was needed to avoid years of "bitter division" between Westminster and the devolved governments. We are never going to accept Brussels [being] replaced by London.

Writing in the Guardian, Mr Jones added: "If they are not careful, people's sense of disengagement with Brussels will simply attach itself to London".

The slightly awkward shots of Theresa May and Carwyn Jones at the Liberty stadium give the impression of a workmanlike relationship at best.

"We need to see some evidence of listening", she said. "Otherwise people in Wales are going to start saying, well, the government is listening to the Scots, we need to be like them".

Leanne Wood, Plaid Cymru leader, insisted "all options should be on the table" - including a Welsh independence referendum - when it comes to the future of Wales when Britain's divorce from the European Union is over.

She said there would be "clear consequences" for Mrs May if she was "not listening" to the rest of the United Kingdom during her negotiations.

As the Prime Minister visited the country this morning ahead of triggering Article 50, Ms Wood told the BBC that "all options should be on the table".

"Plaid Cymru put down our political differences aside with the Welsh Labour Government to produce a White Paper to outline what should happen to ensure that Wales is kept within the process".

Despite 52 per cent of Wales voting to leave the EU, Plaid Cymru is rallying against hard-Brexit and is pushing for single market access in the up-coming EU negotiations.
