First Minister Alex Salmond is returning from official business in Spain to lead discussions with Holyrood opposition leaders and union representatives in Edinburgh.

The talks started yesterday amid fears that plans to build two new aircraft carriers could be downgraded. Doubts have also been raised about the future of RAF bases in the north east.

Politicians are aiming to agree a joint submission to the UK Strategic Defence and Security Review in the hope of protecting jobs and skills in Scotland.

A spokesman for the First Minister said: "That's the objective on the basis that if we can all speak with one voice, then the strength of Scotland's voice will be maximised.

"The fact that all the political parties are actively engaged in this process is of itself encouraging. It shows a willingness."

Deputy First Minister Nicola Sturgeon represented the SNP administration in Mr Salmond's absence yesterday, saying the initial talks were "very productive".

The Ministry of Defence is under pressure to cut its 36.9 billion annual budget by up to 20%. UK Defence Secretary Dr Liam Fox is expected to make an announcement at the end of October.

Concerns about the carriers were raised last week after BAE systems chief executive Sir Ian King told the Defence Select Committee in the House of Commons that the company had asked to consider a number of

options ranging from "one carrier to no carriers".

There are fears that any downgrading of the programme could cost thousands of jobs at shipyards on the Clyde and at Rosyth.

This afternoon's meeting is expected to bring together Labour leader Iain Gray, Liberal Democrat leader Tavish Scott, Tory leader Annabel Goldie and union representatives at St Andrew's House in Edinburgh.
