The alarming scale of Islamic extremism within the UK has been laid bare with security services revealing that around 23,000 known jihadists are now in Britain.
There is now an army of extremists, with 3,000 jihadis on an active watchlist plus another 20,000 who have been investigated before and are believed to represent some risk.
The Westminster killer and recent Manchester bomber did not feature amongst the top 3,000 being actively investigated, for instance.
Anyone can see that the scale of this terror threat is huge and likely to only get bigger. The security services are being stretched to breaking point and need to be backed with the resources, whilst those for whom there is evidence of extremism should be locked up or deported before any more innocent people are murdered on the streets of Britain.
