Scotland's SNP Brexit Minister Mike Russell has clashed with former Brexit Minister David Jones over whether the UK should stay in the customs union.

The fiery exchange follows the DUP blocking of Theresa May's Brexit border deal, branding it "Unionist nightmare".

Clwyd West Tory MP Jones, who led the Leave campaign in Wales, was facing Russell on the BBC's Victoria Derbyshire programme and rejected the idea that the solution was for the UK as a whole to remain in the customs union and single market.

Mr Russell disagreed, saying: "David, you don't know much about this, you were so extreme they got rid of you in [Department for Exiting the European Union]."

Mr Jones replied: "Mr Russell you're customary rudeness doesn't help on this occasion."

Mr Russell later said: "I suffered David Jones for a year on the joint ministerial committee. He doesn’t know what he’s talking about, he’s making a mess of it, so are the people around him. In the name of God, stop this nonsense because it is just causing disaster and being lead to disaster by people like David Jones.

Mr Jones countered by saying: "Mr Russell was probably the biggest impediment to the negotiations between the British Government and the devolved administrations and frankly he's’ just displayed admirably why he’s a danger to the whole process of Brexit and the smooth withdrawal from the European Union."

Mr Russell replied: "This is just nonsense, there can’t be a smooth withdrawal, it’s impossible. "
