Participants clash over possible job losses at Faslane

The debate has turned to the familiar issue of the Trident nuclear deterrent, which is based at Faslane Navy base on the Clyde.

"Trident is probably the least efficient job creation scheme you can imagine," says Patrick Harvie. "Getting rid of Trident will not close the base, it will continue to have a non-nuclear function, but the opportunity to re-invest in the really socially useful things that we do need," he says.

Ruth Davidson replies: "Faslane is the biggest single-site employer in Scotland and if you go and speak to people in Helensburgh and surrounding areas, they don't want the [nuclear warhead bearing] submarines to go".

Campaigners clash over best way to get rid of nukes

The penultimate part of the debate is about international affairs.

Scottish Conservative leader Ruth Davidson argues that the best way of reducing the number of nuclear weapons in the UK and around the world is to work with other countries towards this goal.

Scottish Greens co-convener Patrick Harvie says that Scotland is committing to "unilateral rearmament" and a future of "psychopathic weapons" if it remains part of the UK.

Ayatollah Ali Khamenei called on Iran's Revolutionary Guards to mass produce missiles and said the nuclear negotiations were not the place to discuss Tehran's defence programme.

"They expect us to limit our missile programme while they constantly threaten Iran with military action," Khamenei was quoted as telling the IRNA news agency.

Iran and the United States, France, Germany, Britain, China and Russia will reconvene in Vienna on Tuesday for a new round of nuclear talks.

UK Defence Secretary Philip Hammond revealed details of a small internal leak of radiation on Thursday as he announced that the nuclear submarine HMS Vanguard is to have its reactor refuelled at a cost of £120 million.

Mr Coaker and Ms Curran said there were "significant questions" about the handling of the incident, particularly the two-year delay in making it public.

"The ungrounded threats to Russia from the US and NATO over its Ukrainian policy are regarded by us as an unfriendly gesture and allow us to announce force majeure," the unnamed source was quoted as saying by the state-owned RIA Novosti news agency.

"We are ready to take this step as a response to the Pentagon's statements about suspension of engagements between the armies of Russia and the US," the source added.
