Ringleaders plotting more violent demonstrations in Britain were warned by the Government “we are watching you” as it sought to stop the “summer madness” from spreading.Home Office minister Lord Hanson stressed the police would be seeking to track individuals involved in conspiring to encourage violent protests.He also told people considering taking part in violent incidents, after the Southport stabbings, that they should be prepared to end up in court and possibly go to jail.After a series of outbreaks of violence, he told LBC Radio: “We want to send a signal to those people who are potentially undertaking conspiracy that they know that we will use intelligence-led policing, we will use all the tools available to make sure that we prevent this activity if at all possible and if it does happen that they need to know that they will face the full force of the law.“This is not about peaceful protest, this is about criminal activity.”
