Quick Summary

Britain is holding a record number of 275 people in prison for terrorism offenses at the end of June, with the majority convicted for Islamist extremism, according to Home Office data. This marks an increase from last year and surpasses previous peaks since records began in 2010. Of those incarcerated, 57% are associated with Islamist-extremist views, while 29% hold extreme right-wing beliefs. The surge in arrests follows the proscription of Palestine Action, which has led to a sharp rise in terrorism-related detentions; over half of all such arrests since 9/11 occurred within the past year.

Story summary

As of June end, 275 convicted terrorists are imprisoned in Britain, marking a new record since data collection began in 2010, when there were only 126. This is an increase by seven percent from the previous year and surpasses the earlier peak of 273 recorded at the end of March. The majority, about 57%, adhere to Islamist extremist views, while around 29% have extreme right-wing beliefs. About 14% fall under 'other' ideologies. Following the banning of Palestine Action, a protest group, thousands have been arrested. Additional data from the Ministry of Justice showed that among those without specified ideology, four were categorized as 'far-left or anarchist', eight held multiple ideologies, and twelve were designated as 'other'. This surge highlights Britain's evolving approach to counterterrorism measures.
