Nia Griffith MP, Labour’s Shadow Defence Secretary, commenting on the Prime Minister’s failure to explain when she knew about the Trident test blunder, 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.”
