England could be hit by more riots next northern summer - possibly during the London Olympics - without urgent action to tackle the causes and to improve policing in potential hotspots, a government-commissioned report warned yesterday.
It said some factors behind the looting, such as poverty, joblessness and grievances about the police, remained potent problems in parts of major cities.
The investigation by the independent Riots, Communities and Victims Panel also said victims of the riot violence were struggling to get compensation.
Darra Singh, the panel's chairman, said: "While deprivation is not an excuse for criminal behaviour, we must seek to tackle the underlying causes of the riots or they will happen again."
Maeve Sherlock, a panel member, said there was widespread anger, in areas hit by trouble, over inequalities and injustices with people pointing to bankers' bonuses and the MPs' expenses scandal.
