Ed Miliband: No excuses for rioting
Labour leader Ed Miliband has said there can be "no excuses" for the violent behaviour which broke out in London and spread to other cities.
Visiting Peckham in south London, where shops were looted, he said restoring public order must be the priority.
He urged the government to provide resources to help people who have lost their homes and businesses.
The PM cut short his holiday to chair a meeting of the Cobra emergency committee in Downing Street on Tuesday.
David Cameron announced that Parliament would be recalled for a day on Thursday, for a statement from him and to allow MPs to debate the events of the past few days.
Looting and violence broke out across London on Monday night - the third night in a row following trouble in Tottenham, north London, on Saturday.
It began following a protest against the fatal shooting by police of a 29-year-old local man, Mark Duggan, last week but spread across various London boroughs - and to other cities including Birmingham and Liverpool.
Mr Miliband visited Peckham with his deputy leader Harriet Harman - who is the local MP for the area. He said: "There can be no excuses for the violence, the intimidation of people. That can never be excused, that can never be justified. That is why the immediate priority is to restore public order and public safety."
He added: "We can't allow parts of London to have, essentially, no-go areas where people feel frightened on the streets. There are people who have lost homes, lost businesses."
He urged the government to provide help for those who had to rebuild their homes or businesses and would need temporary accommodation, he said he had heard tales of heroism from people in the area.
Ms Harman said people in Peckham had been "really terrified" and must be able to feel safe again. She told the BBC the police faced "difficult operational decisions" about how to handle events but she was sure they were determined to restore peace to the streets.
They are among various politicians visiting affected areas in the aftermath of the riots - Mr Cameron visited Croydon and Lambeth in south London.
London Mayor Boris Johnson was confronted by angry residents and workers on a visit to Clapham Junction while Deputy Prime Minister Nick Clegg is visiting Birmingham - where more than 100 people have been arrested over a rampage through the shopping area.
