The Prime Minister Theresa May will travel to Wales on Tuesday to warn that an unstable coalition of divisive nationalists could make Jeremy Corbyn Prime Minister, and undermine the chances of success in our negotiations to leave the EU. 
After chairing Political Cabinet with her Conservative Team, Theresa May will travel to a range of seats in Wales to speak at a political rally and visit a business. 
She will warn that alliances between Plaid and Labour in the Welsh national assembly could provide a blueprint for similar coalitions in the rest of the UK, saying the Brexit referendum “should have been a wake-up call for a generation of politicians who have taken the people for granted for too long. But instead those same politicians have closed ranks, with Plaid Cymru propping up Labour in a direct example of the kind of collaboration we should expect in Westminster if Jeremy Corbyn and Leanne Wood get their way.”
In an article for Tuesday’s Western Mail the Prime Minister Theresa May writes: 
“This election is not about the kind of tribal politics that has held sway in Wales and elsewhere for many years. It is not about calling in old favours or relying on past allegiance. It is about the future.
“It is an opportunity to provide this United Kingdom with the strong and stable leadership it needs to see us through Brexit and beyond. It is a chance to lock in the economic progress we have made together over the past seven years. And it is your chance to strengthen Britain’s hand as we negotiate with Europe to ensure we get the right deal for ordinary working people everywhere. A deal that will help us build a stronger Wales, as part of a more secure Britain.
“Securing that deal is my priority and we have the plan to do it. A plan to regain control of our own money, our own laws and our own borders, and to be free to strike trade deals with old friends and new partners all around the world.
“Yet our Labour, LibDem and Nationalist opponents – Plaid Cymru here in Wales and Nicola Sturgeon’s SNP in Scotland – are already seeking to disrupt our negotiations, even as 27 other European countries line up to oppose us. That approach can only mean one thing – uncertainty and instability, bringing grave risk to our growing economy with higher taxes, fewer jobs, more waste and more debt. Only this week, Carwyn Jones pledged his support for Labour’s plan to add £500 billion of borrowing to Britain’s debt – undoing all the progress we have made together over the past seven years at a stroke.   
“That is why I will be fighting to earn every vote I can in this election, because every vote I receive will strengthen my hand as I negotiate with the Prime Ministers, Presidents and Chancellors of Europe. Every vote I receive will help me secure the best deal to strengthen our economy. Every vote I receive will be a vote to give me the mandate to deliver for Britain.  
“Ten months after voters across Wales helped to start this journey, Labour in Wales – and their partners in Plaid Cymru – remain determined to disrupt the result.
“So your vote on June 8th really matters to the future of our country. It’s a choice between strong and stable leadership in the national interest, or Jeremy Corbyn in Downing Street at the head of a coalition of chaos. 
“And it is a chance to cast a positive vote for the strong and stable leadership we need to deliver on the democratic will of the British people, to strengthen Britain’s hand in the negotiations to come, and to reject the kind of ‘politics as usual’ that has let people down in Wales for too long.”
