The Mayor of London, Boris Johnson, is to review performance in tackling crime and bringing offenders to justice at 2014's first quarterly meeting of the MOPAC Challenge Board.
The Mayor will chair the Board, which will focus particularly on the progress of the police and London's criminal justice agencies in achieving a 20 per cent reduction in justice system delays.
For the first time the Challenge Board will compare data on the average time taken from offence to completion in London's Crown Courts, where serious criminal cases are tried.
A report by the Centre for Social Justice says the arrests of more than 200 leaders of London street gangs in the wake of last year's riots has led to an increase in chaos, violence and anarchy in the capital.
It says the removal of 'elders' from the streets backfired because it created a power vacuum in which younger and more hot-headed members seized control of gangs.
Almost one in eight prisoners have illegal drugs in their system and another one in five are taking methadone, a jail watchdog has said.
Life behind bars for the 1,260 inmates at Pentonville Prison is "a microcosm of society outside", David Miller, chairman of the Victorian-era jail's independent monitoring board (IMB) said.
