Simon Hughes, Liberal Democrat deputy leader and south London MP for Bermondsey and Old Southwark, warns people to stay inside and ensure young people are doing the same:
"Things are now becoming very serious in many areas of London including in my own borough of Southwark.
"The police must now have our support and they must be free to take the action they feel necessary to restore peace in our communities.
"In boroughs like Southwark, unless people have urgent reasons for being out on our streets, they should stay inside.
"I call on all parents, elders and other family members now to make sure that their teenagers and young adults stay inside and are not out on the streets.
"And there is just one simple message for young people. Don't give in to the temptation to trash your own communities – these are the places which we all need for our future jobs, housing and prosperity."
