The chief coroner hearing inquests into the deaths of two men killed in the attack on Heaton Park synagogue last year will ask the Home Secretary to open a full public inquiry into the incident instead.
Judge Alexia Durran, Chief Coroner of England and Wales, said she will write to Home Secretary Shabana Mahmood to recommend the inquests be converted into a public inquiry.
Inquests were planned into the deaths of Adrian Daulby, 53, and Melvin Cravitz, 66, following the attack by Jihad al-Shamie, 35, a Syrian-born British citizen, last October.
At a hearing earlier this month, Home Office lawyers applied to withhold some information from MI5 being made public at a future inquest due to national security concerns.
Inquests have no mechanism to hold secret or private hearings, excluding the press and public.
To carry out a full investigation, involving hearing sensitive material in private, would require a public inquiry – which can hold some of the hearings behind closed doors with press and public excluded.
Judge Durran made the decision to ask for a public inquiry to be established following the pre-inquest hearing on September 4.
At the hearing, lawyers for the government said if the MI5 material was released, it would harm national security.
Lawyers for the families of the two victims questioned why private hearings were necessary for the disclosure of MI5 material, as the authorities had stated publicly that al-Shamie was not known to security services.
Al-Shamie launched his attack on October 2 last year by driving into the perimeter gates of the synagogue, then attacking worshippers with a knife while wearing a fake suicide belt.
Cravitz died from multiple knife wounds, while Daulby was killed by a bullet fired by armed police scrambled to the scene as he blocked the synagogue doors while al-Shamie tried to get in.
