The hitman serving time for executing gangster Euan Johnston has failed to convince senior judges to allow his murder conviction appeal to go ahead.

Lawyers acting for David Scott, 33, told the Court of Criminal Appeal on Friday that they should be allowed to continue working on the hood’s cause.

Judges Lord Carloway, Lord Turnbull and Lord Menzies heard the lawyers had identified “fresh” issues from Scott’s trial which show he may have fallen victim to a miscarriage of justice.

But on Friday, Lord Carloway, Scotland’s most senior judge, said the “fresh” evidence identified by the lawyers didn’t meet strict legal tests to show that Scott was the victim of a miscarriage of justice.

Scott, originally of Glasgow, was handed a life sentence in May 2018 at the city’s high court in which he was ordered to serve a minimum of 22 years.

Jurors heard how Scott shot Johnston twice in the head in the attack in Glasgow in November 2016. One bullet went through his brain.

Lord Carloway spoke as Scott watched the proceedings via video link from prison.

He said: “The court is not persuaded that there is anything of any substance to these new grounds of appeal. “The court is not satisfied that there any grounds that allow this appeal to continue.”
