It has been reported that Theresa May was told about the test of a Trident missile that misfired less than a week before she held a House of Commons vote on renewing the £40bn nuclear system. This week she repeatedly refused to deny reports that a serious malfunction had occurred, saying the Government would not get into operational details. Downing Street is facing growing accusations of a cover-up, because on 18 July the Prime Minister stood up in the Commons to ask MPs to vote for the renewal of the Trident programme without telling them about any possible problems. In that debate, Mrs May said she would be willing to authorise a nuclear strike that could kill 100,000 people, and the Commons voted overwhelmingly to replace the programme.
