Speaking to reporters after chairing his second Cobra meeting in two days, the prime minister said: “That should send a very powerful message to anybody involved, either directly or online, that you are likely to be dealt with within a week.
“Nobody, but nobody, should be involved themselves in this disorder.”
Mr Farage proposed a plan to stop the rioting which involved ending “mass immigration” and getting “all the police chiefs across the UK together and to say to them, start policing even-handedly”.
