Home Secretary Theresa May is to return from her summer holiday following a second night of violence in London.

More than 100 people have been arrested and 35 officers injured as police vehicles were damaged and shops looted in some parts of the capital.

Following riots in Tottenham on Saturday, disorder spread to Enfield and Walthamstow in north London and Brixton in the south of the city.

Deputy Prime Minister Nick Clegg called the rioting "opportunistic theft".
