The Welsh Government will need to reassess Wales’ place in the union if other nations leave as a result of a hard Brexit.
The Welsh Government’s Brexit Minister will make the comments at the National Eisteddfod in Llanrwst in Conwy today.
“Increasingly there has been a renewed interest in what Wales would do if a hard Brexit brought about the departure from the union of other nations,” Jeremy Miles is expected to say.
“We believe that the UK is a voluntary association of nations, so it follows that we also recognise that some component parts of the United Kingdom may no longer choose to be part of it.
“And if that were to happen, any sensible government would have to reassess Wales’s place in a changed UK.”
But he added that the Welsh Government would aim to stay in the UK if it could: “We continue to believe in the union. Our priority is to remain and reform.”
Following the European Parliament election in May, the Welsh Government is now officially backing a second referendum on the UK’s membership of the EU, and will campaign to remain in the EU if one is held.
Mr Miles will also say in his comments that the UK Government’s attitude towards devolution needs to “change fundamentally”.
“Currently, it seems still to have a profound ambivalence about devolution,” he will say.
“Or worse, an attitude that if we behave ourselves, the UK government will out of the goodness of its heart, allow us some limited powers of self-government.
“A ‘get what you’re given’ type of devolution.”
