Guess

Seems someone other than the English hates Jack (the English used their propensity to violence, "in Europe and with our empire".) Straw. At least I presume it's someone not English...
BBC.

A man has been arrested on suspicion of making threats to kill the former Foreign Secretary Jack Straw and the Home Secretary Theresa May.
The threats were allegedly made in a phone call to the office of Rossendale and Darwen MP, Jake Berry, on 18 April.
Lancashire Police arrested a 33-year-old man who works for Blackburn with Darwen Council.
The suspect, who is from Blackburn where Mr Straw is the local MP, has been released on police bail.

Now colour me suspicious and invoke the name of Qatada but I do suspect that the person involved will have a pretty much un-English name and has a damned good chance to have an affinity with the name Mohammed. I also suspect he isn't going to be C of E either. What I do know about Darwen is the proportion of Muslim population (19.4% or 26,674 people) is the third highest among all local authorities in the United Kingdom and the highest outside London (the Islamic republic of Tower Hamlets no doubt). 20.4% of the districts population belongs to those of a Pakistani, Bangladeshi origins, making it the highest percentage in any UK region, and almost four times higher than national average.
So...
Making threats against a former Home Secretary who'd already criticised veils and Theresa May who is trying (unsuccessfully so far) to remove the cancerous growth of an Islamic terrorist from our shores and who do you suspect the person making the threats will be?
Not that I expect the BBC to tell us any time soon.
