Nuclear missiles have been based at the Faslane naval base for 41 years
David Cameron has warned the SNP against trying to use Holyrood powers to block a new generation of Trident nuclear submarines on the Clyde.
However, the SNP leader Alex Salmond said majority opinion in Scotland was anti-Trident.
He said there could be "no complaint" if MSPs sought to reflect that.
The Conservative leader's comments and those of Scotland's first minister feature in a BBC Scotland documentary to be broadcast on Sunday night.
Nuclear missiles have been based at the Faslane naval base for 41 years.
Holyrood and the Search for Scotland's Soul will be broadcast on BBC One Scotland at 2220 BST.
