A slim majority of Scots support nuclear disarmament, according to a poll for STV.

The survey by Ipsos MORI found 51% of those asked said they supported the UK scrapping all of its nuclear weapons, while 40% would keep them.

When asked if they supported the UK removing the weapons even if other countries keep theirs, however, only 44% agreed, while 46% said they were opposed.

The poll comes as the Labour Party continues a review of its policy on nuclear weapons, with shadow home secretary Andy Burnham conceding this week it may be "impossible" for the party to reach an agreed position.

Mark Diffley, director at Ipsos MORI Scotland said: "Although the issue of nuclear weapons is not a devolved issue and is therefore not likely to be at the front of voters' minds ahead of May's Holyrood election, it is still very topical and is being keenly debated, particularly in the Labour Party.

"These results show that Scots are split on the issue but are more likely to oppose scrapping nuclear weapons if they are aware that other countries will keep theirs."

The telephone poll of 1000 adults in Scotland was conducted between February 1 and 7.

Meanwhile, a union representing defence workers is to hold a special conference so that the "voice of working people" can be given on the future of the Trident nuclear missile system.

GMB members from areas including Faslane, Barrow, Devonport, Coulport, Rosyth and Merseyside will meet in Newcastle on February 25.

The union's policy is in favour of Trident renewal, arguing that tens of thousands of jobs depend on the programme.
