Michael Fallon told MPs the Trident nuclear system was successfully tested
The Defence Secretary was hauled to the House of Commons this afternoon amid allegations of a Government cover-up.
During a TV interview yesterday, the Prime Minister ducked questions about a Sunday Times report an unarmed Trident II D5 missile veered off course after being launched from a Royal Navy submarine off the coast of Florida in June 2016.
But Mr Fallon told MPs: "Contrary to reports in the weekend press, HMS Vengeance and her crew were successfully tested and certified as ready to rejoin the operational cycle.
"We do not comment of the detail of submarine operations."
He added: "The capability and effectiveness of the UK's independent nuclear deterrent is not in doubt.
"The Government has absolute confidence in our deterrent and in the Royal Navy crews who protect us."
Downing Street had earlier admitted Theresa May had been informed about the test before setting out the case for renewing the Trident programme to MPs in July last year.
House of Commons’ Speaker John Bercow dismissed a request from Tory MP Jacob Rees-Mogg for today’s proceedings to be heard in private in order to prevent MPs giving “succour to our enemies”.
