First Minister Nicola Sturgeon’s demanded that the House of Commons should have been given full disclosure of the event in June last year before a vote was passed to approve the renewal of Britain’s independent nuclear deterrent the following month.
The Scot also accused Theresa May of facilitating a "cover-up", after the Prime Minister refused to answer questions on the failed missile testing shorting before the Commons vote, which until January had remained confidential.
Fifty-four SNP MPs voted against the renewal of the deterrent, which is based at Faslane on the Clyde, after having called for a vote to be delayed.
Nato only has three nuclear powers – Britain, France and the United States – the nuclear deterrent is a critical part of the organisation's platform.
Nicola Sturgeon's Trident criticisms have come under fire from Labour MP Gisela Stuart
If you are a member of Nato you also subscribe to a nuclear deterrent
A post-independence SNP Scottish government has vowed to remove the weapons system from the country if it ever splits from the UK.
Speaking to Express.co.uk, Ms Stuart, MP for Birmingham Edgbaston, said: “I always found the SNP’s position on Trident curious.
“On the one hand they argued against Trident, but if I remember rightly argued in favour of remaining a member of Nato.

“If you are a member of Nato you also subscribe to a nuclear deterrent, so even if you do not have nuclear weapons yourself, you do commit to making your aircraft, for example, available in the case of a nuclear strike.

“So I think their defence position has always been curious anyway, and to my mind remains curious.”
But the Labour MP, who played a key role in the Vote Leave campaign, declared it was unlikely Scotland would ever gain independence, allowing themselves to rid the country of nuclear weapons.
Ms Stuart described the First Minister’s threats of independence as little more than “good politics” as she looks to broker a separate Brexit deal for Scotland.

Since Britain’s historic vote to leave the European Union, Ms Sturgeon has demanded that the SNP be allowed to negotiate a “separate deal” for Scotland, which would see the national retaining its membership of the single market.
She, however, threatened that if her demands are not met she will endeavour to deliver a second Scottish independent referendum, after the SNP failed to deliver victory, with Scotland voting 55-45 per cent to remain part of the UK, in 2014.
Ms Stuart added: “If you consider that the Scottish independence referendum was lost, I cannot see, currently, where an extra support would come from if she had to hold another referendum.
“I view a lot of the Nicola Sturgeon demands for remaining in the single markets – the threats to temporally leave the single market – as good politics, rather than a genuine threat because I think if she had another independence referendum – where do the extra votes come from?”
