Theresa May is facing calls to come clean over a failed test of the Trident nuclear deterrent amid claims the government acted like North Korea in covering up the incident.

The Prime Minister failed to answer several direct questions on her knowledge of the test, which took place weeks before MPs approved the £40 billion Trident renewal programme in July.

The launch of an unarmed Trident II D5 missile from a British submarine off the coast of Florida in June malfunctioned and veered towards the US instead of Africa.

Mrs May did not mention this test in a speech to MPs before the House of Commons vote, in which she urged them to back renewal, leading to allegations the malfunction has been covered up.

First Minister Nicola Sturgeon called for “full disclosure” about who knew what and when, and Labour leader Jeremy Corbyn described the failed test as “a pretty catastrophic error”.

Labour peer and former senior ­Royal Navy officer Admiral Lord West added it was “bizarre and stupid” to not tell anyone.

Mrs May said she had “absolute faith” in the Trident missiles. However, she repeatedly failed to address whether she knew about the failed test before her speech to MPs.

She told the BBC’s Andrew Marr Show: “When I made that speech in the House of Commons, what we were talking about was whether or not we should renew our Trident, whether or not we should have Trident missiles, an independent nuclear deterrent in the future.

“I think we should defend our country, I think we should play our role in Nato with an independent nuclear deterrent.

“Jeremy Corbyn thinks differently, Jeremy Corbyn thinks we shouldn’t defend our country.”

Asked again about her knowledge of the test, Mrs May replied: “The issue we were talking about in the House of Commons was a very serious issue.

“It was about whether or not we should renew Trident, whether we should look to the future and have a replacement Trident. That’s what we were talking about in the House of Commons, that’s what the House of Commons voted for.”

When Mr Marr asked about her knowledge of the test for a final time, Mrs May said: “There were tests that take place all the time for our, regularly, for our nuclear deterrents.

“What we were talking about in that debate that took place was about the future.”

Previous tests have been publicised by the government.

Mr Corbyn seized on suggestions the missile veered from its intended target near Africa towards the US.

The Labour leader said: “I think this failure is something that ought to pause everyone for a moment and just think what happened.

“We understand the Prime Minister chose not to inform parliament about this and it’s come out through the media some months later.

“It’s a pretty catastrophic error when a missile goes in the wrong direction and whilst it wasn’t armed, goodness knows what the consequence of that could have been, I think we need a serious discussion about that.”

SNP leader Ms Sturgeon, meanwhile, tweeted: “This is a hugely serious issue.

“There should be full disclosure of what happened, who knew what/when, and why the House of Commons wasn’t told.”

Admiral Lord West told BBC Radio 4’s The World this Weekend that the government had “made a bit of a pageant” of previous missile tests.

He said: “From what the government says there was a minor glitch with the missile and they’re quite happy with the missile.

“In which case go ahead and let people know, otherwise we’re a bit rather like the Soviet Union used to be, or like North Korea or China, where they won’t admit to things going wrong when you’re actually testing them to see if they do or don’t go wrong.”

He added: “I think it is bizarre and stupid that they didn’t say that there had been a firing and that there had been a missile malfunction and that it was a minor fault.”

The cause of the failure remains top secret but questions could be asked over the government’s failure to publicise the failed test

Labour MP and former defence minister Kevan Jones said: “The UK’s independent nuclear deterrent is a vital cornerstone for the nation’s defence.

“If there are problems, they should not have been covered up in this ham-fisted way.

“Ministers should come clean if there are problems and there should be an urgent inquiry into what happened.”

A government spokesman said: “The capability and effectiveness of the Trident missile, should we ever need to employ it, is unquestionable.

“In June the Royal Navy conducted a routine unarmed Trident missile test launch from HMS Vengeance, as part of an operation which is designed to certify the submarine and its crew.

“Vengeance and her crew were successfully tested and certified, allowing Vengeance to return into service. We have absolute confidence in our independent nuclear deterrent.

“We do not provide further details on submarine operations for obvious national security reasons.”

Nia Griffith, Labour’s Shadow defence secretary, said: “This report of a Trident missile veering off course during a test is clearly a very serious matter indeed, and we need to know exactly what happened.

“Furthermore, it is completely unacceptable that today the Prime Minister chose to side-step questions on the test, and would not even tell us when she knew about the incident.

“I am demanding the Prime Minister come to parliament tomorrow to give a full explanation to MPs.”

Kate Hudson, general secretary of the Campaign for Nuclear Disarmament, said the failed test “would have impacted on the debate in parliament on Trident replacement”.

“So the government’s motivation for holding back this vital information is clear,” she added.

“Instead this crucial information has been revealed by a senior naval figure rather than by government at the appropriate time to inform the parliamentary debate.

“This is shocking behaviour on the part of our government and it is profoundly to be hoped that parliamentary opposition forces will hold government to account for withholding information.”
