The Labour leader Ed Miliband calls for a national discussion while visiting Hackney, one of the places hit by rioting.
Mr Miliband has pledged that if the Government does not launch a public inquiry into the riots which swept England, then his party will conduct one.
"I am determined to make sure that, if the Government doesn't conduct this national conversation that we need, we will do it ourselves at the Labour Party."
During a visit to local businesses in Hackney he said, "We need a proper national conversation, a proper commission of inquiry looking at the issues involved, because simplistic solutions will not work."
''After all other major disturbances in Britain there has been a proper inquiry - that is why the Government needs to get on with it," he added.
The Labour leader said those affected by the lawlessness in the area had told him the issues behind the looting included problems with parental responsibility, the relationship between the police and the public, and the lack of opportunities for young people.
