Theresa May refuses to answer questions on Trident 'misfire'

Theresa May has refused to say whether she knew that a Trident missile reportedly misfired just weeks before a Commons vote on the future of the nuclear deterrent.

The prime minister declined four times to answer questions about whether she was aware that the launch of an unarmed Trident II D5 missile from a British submarine off the coast of Florida in June had veered off course.
