The Mayor of Greater Manchester has called on the Government to initiate a national review of event security.
It follows calls from families of the victims of the Manchester Arena attack to enhance security at major venues.
They come in response to the independent Kerslake report into the bombing nearly 2 years ago.
Assurances have also been made that emergency services will work closer together to avoid delays responding to similar incidents in the future.
Twenty-two people died when suicide bomber Salman Abedi, 22, detonated a device in the foyer of the arena at the end of an Ariana Grande concert on May 22 2017.
The update into the report revealed Greater Manchester Fire and Rescue Service (GMFRS) had undertaken a "full root and branch review" after concerns over its delayed response to the emergency.
Media regulator the Independent Press Standards Organisation (IPSO) was compiling guidance on reporting major incidents after some bereaved relatives said they felt "hounded" by the press in the aftermath.
Figen Murray, the mother of victim Martyn Hett, 29, wants the introduction of "Martyn's Law" - which would make metal detectors and bag searches obligatory for big public venues.
I believe there is a clear case for a thorough review of security measures at major sporting and entertainment event venues to establish clearly understood mandatory standards and I call on the Government to initiate one. We need to have clear minimum and mandatory standards at all venues so there is clarity for operators and confidence for the public
