Paul Masterton has stepped down from his role as a government aide at the Home Office. 

The Scottish Tory MP resigned after he voted to rule out a no-deal Brexit under all circumstances at last night's Brexit vote.

Mr Masterton told the Barrhead News: “Last night, I took the difficult decision to vote against the Government and resign my role as a PPS in the Home Office.

"I have been clear that, whilst I believe we must honour the result of the EU Referendum, I cannot support the UK leaving without a deal. Last night, I honoured that position."

Last night, MPs voted in favour of an amended Government motion to reject a no-deal Brexit at any time and under any circumstances by 321 votes to 278, majority 43.

Mr Masterton was one of 17 Conservatives to vote to rule out the no-deal.

Nicola Sturgeon praised Mr Masterton's decision at First Minister's Questions on Thursday.

She said: "With the exception of Paul Masterton, every single Scottish Conservative MP has chosen to put loyalty to the Prime Minister ahead of the Scottish people."

Scottish Secretary David Mundell was forced to defend himself after he defied Theresa May and abstained on the vote last night.

He tweeted: "I’ve always opposed a no-deal Brexit. The House made its view clear by agreeing the Spelman amendment, I didn’t think it was right for me to oppose that.

"The PM has my full support in her objective of leaving the EU with a deal to deliver an orderly Brexit."
