Theresa May in Wales as part of Brexit tour of UK

With exactly a year to go until Britain leaves the European Union, the Prime Minister will spend the day visiting each of the UK's nations, focussing on what she calls 'the world's most successful union.'

But as she prepares to visit Wales, she'll also face criticism from the First Minister who says that 'the people of Wales still have no idea about the post-Brexit deal the Prime Minister wants with Brussels.'

When she arrives here later, Theresa May will host a roundtable meeting with businesses at a location in the Vale of Glamorgan.

She'll start the day with textile workers in Ayrshire in Scotland before flying to Newcastle to meet parents and toddlers.

She'll have lunch with farmers near Belfast before flying to the Vale of Glamorgan.

After that she'll end the day with a group of Polish citizens now living in West London.

The Prime Minister will use the day to highlight her message that 'together we amount to so much more than the sum of our parts and our Union is an enormous force for good.'

I understand that Theresa May won't be meeting Carwyn Jones during her flying visit. Number 10 says that's because none of her visits are aimed at meeting non-politicians.

It hasn't stopped him expressing a critical view of her leadership on Brexit.

The First Minister says that with a year to go and nearly two years since the referendum, Theresa May still hasn't properly explained what sort of relationship she envisages between the UK and the EU.

If today isn't about meeting other politicians, neither is it about resolving the dispute between UK and Welsh and Scottish Governments over how to share out powers currently with Brussels when they return to the UK. You can read the background to the dispute here.

Both sides say they want to reach agreement but don't expect that to happen today. Number Ten says it's not part of its focus for the visits and I gather that the Welsh Government hasn't received any hint of a further concession which could end the dispute. There are also no further meetings scheduled yet.

Speaking ahead of Thursday's visit, Theresa May was standing by her government's position:

Plaid Cymru would certainly like to hear some sign of movement in the dispute today.

The party's Steffan Lewis is the architect of a Continuity Bill which would overturn the Withdrawal Bill as it affects Wales.

He said:

Our latest Barometer poll, published last week,showed that despite voting to leave in 2016, people in Wales are still divided between leaver and remainers.

The Prime Minister will try to use her day-long tour to try to heal those divisions.
