Diolch. Well, I hope that means, as they said, that that will deliver operational independence from politicians, especially.

But, as I said here in March 2019 on a different subject, the Welsh Government and Plaid Cymru White Paper, 'Securing Wales' Future', which called for continued membership of the EU single market, would mean no control of our borders, our trade and our laws, and would therefore be Brexit in name only. 

Speaking here last week, the First Minister extolled the virtues of Wales and the UK being inside the single market, although he appeared to back-pedal on this yesterday after Keir Starmer's statement that Labour has ruled out rejoining the single market as party policy, but claimed that he could remove trade and travel barriers nonetheless. What advice would you therefore give as Counsel General to both the First Minister and Mr Starmer about the legal barriers applying to this?
