MI6 and a senior detective have been accused of failing to disclose vital evidence in the death riddle of spy Gareth Williams.
A coroner suggested that the counter-terror officer, Detective Superintendent Michael Broster, was not being “completely impartial” towards secret services during the Scotland Yard inquiry.
Coroner Fiona Wilcox and the family's lawyer both delivered angry outbursts after it emerged that nine computer memory sticks and a black bag were overlooked for 21 months after the death.
The lead detective on the case was told about the evidence only on Monday.
Dr Wilcox also stated at Westminster Coroner's Court that Mr Broster was offering “total non-sequitur” reasons for not passing on the evidence.
