A record 400 arrests were made for terror-related offences in Britain in the year to the end of September 2017.
The figures have been released by the Home Office a day after an alleged plot to kill the Prime Minister was revealed.
There have also been allegations that Prince George may have been the target of a separate plot.
The total included 64 arrests in connection with attacks in Westminster, Manchester, London Bridge, Finsbury Park and Parsons Green.
Of the arrests made over the year, 115 resulted in a charge, 213 were released without charge, 60 were released on bail pending further investigation, 11 faced “alternative action”; and one case was pending.
Out of those who were charged, 97 (84%) were charged with terrorism-related offences.
