Brexit: US wants to know what's next, says Carwyn Jones

The way power is shared in the UK needs to change radically to ensure the union survives "tensions" created by Brexit, First Minister Carwyn Jones will say in a speech in Chicago.

Otherwise "nothing, up to and including the break up of the UK... would be inconceivable", he will argue.

Mr Jones is touring the United States to promote Welsh businesses.

He told NBC News he had been asked in every meeting in the US: "What happens next with Brexit?"
