SNP MPs lined up to oppose the decision to renew the UK's nuclear armed submarine fleet - despite the party's policy of supporting the nuclear-armed NATO.
During the debate, SNP members failed to explain why they wanted to remove nuclear weapons from the UK, at the same time as wanting to be part of NATO - which has a nuclear first strike policy.
The Scottish Conservatives are now the only party in Scotland which fully supports retention of a nuclear armed fleet at HMRB Clyde - protecting the UK's defences and maintaining thousands of jobs on the Clyde and elsewhere in Scotland.
Deputy leader Jackson Carlaw said:
"The craven hypocrisy of the SNP on this vital matter of national security is staggering. On the one hand, the Nationalists express moral outrage over nuclear weapons and are now demanding they are taken 200 miles south.
"On the other, Angus Robertson desperately yearns to have a seat at the table in NATO, which supports a nuclear first strike.
"In other words, the Nationalists want to be a member of the nuclear-armed club - at the same time as demanding that nuclear weapons are expelled from Scotland."
"This isn't serious politics - it is small-minded Nationalist nimbyism. And it demonstrates that the SNP's sole aim here isn't to defend our country, but to divide it.
"Many people hold principled opposition to nuclear weapons. But the SNP's defence policy faces so many ways it is fast becoming a national embarrassment."
