“Part of the issue is the sort of amplification of even small numbers on social media that can give the appearance of broad swell of support rather than an actual reflection of the particular numbers of the people who are involved in the act of organising itself,” he said.When it comes to the spreading of misinformation, social media platforms do have incentives in place to try and crack down, but obviously this is a big job.

While liking a page or following a particular account on social media is the user’s choice, there are concerns that extreme content is being “pushed” on people by the companies behind the platforms – by something called “toxic algorithms”.These determine what social media users see in their feeds, based on things like their age, gender and search history.Johnny Ryan, from the Irish Council for Civil Liberties, said he is really worried about the issue.

“If, for example, you’re concerned about or maybe if you’re only curious about the opening of a centre near you to house refugees, that is the kind of signal that these completely wild recommender systems may pick up on and start pushing content about young males of fighting age and all of that kind of stuff,” he said.He added that while there have always been niches of people with extreme views, they have tended to remain in that niche.

“But this system is finding that type of stuff and it is artificially amplifying what otherwise would not be seen by people, and it’s pushing it and recommending it into your feed,” he said.

“We’re seeing this system push the seeds of angst and hate and loathing and despair at people who it has judged are sensitive to receiving it.”He added that young people needed to be given more responsibility and take an active role in their community, which could reduce crime on the estates.

On Wednesday, Mayor of London Sir Sadiq Khan said: "My thoughts are with the family, friends and wider community in Stockwell following the shocking fatal shooting of a 16-year-old boy."This abhorrent violence has absolutely no place in our city. I am in close contact with police leaders – an investigation is under way to find those responsible, and local residents will see increased patrols in the local area."

The period for communities to express their views on plans for the rollout of lower speed limits in residential areas is set to be extended.Infrastructure Minister Michelle Haywood said local authorities would be given six weeks for each region, rather than the statutory two.
