To ask Her Majesty's Government further to the Written Answer by Lord West of Spithead on 21 April (WA 395), how many terrorism prosecutions, including internet-related terrorism prosecutions, have been brought since 2001; and how many of these have been successful. [HL3321]
As set out in my previous Answer, data collected on terrorism prosecutions do not differentiate between online and offline actions and we are unable to accurately separate all internet-related terrorism prosecutions from other terrorism prosecutions, in which the internet may have played a part.
From 11 September 2001 to 31 March 2008, 521 terrorism arrests resulted in a charge. Of this 340 were considered terrorism-related. To 31 March 2008, there were 196 convictions for terrorist-related offences, of which 102 were convicted under terrorism legislation and 94 under non-terrorism legislation.
