MI5 has rejected calls from families of 7/7 bombing victims for a wide-reaching review of its working practices in the light of the attacks.
The bereaved families urged the coroner hearing the inquest into the tragedy to make nine recommendations relating to the security agency, including improving its record-keeping and computer databases.
But lawyers for MI5, also known as the Security Service, said it had learned lessons from the background to the July 7 2005 attacks on London.
They said changes to MI5’s procedures had either been introduced already or carefully considered before experts decided they were not necessary.
James Eadie QC, representing the Security Service, argued against the bereaved families’ calls for the coroner to use her “Rule 43” powers to make recommendations to MI5 to prevent deaths in the future.
“The evidence simply does not give rise to any concern about other deaths in the future or continuing risk,” he said.
Patrick O’Connor QC, barrister for relatives of those killed in the attacks, said the families were not trying to persuade the coroner that MI5 could have prevented the 7/7 bombings.
But they believe the nine recommendations they are proposing would help protect the public, he said.
Four West Yorkshire bombers including Huddersfield student Jermaine Lindsay killed 52 people when they targeted three Tube trains and a bus.
