Caporegime
Disgusting attempts by the remain side to politicise this. Utterly repugnant.
The political murder of a politician is already political. It doesn't have to be politicised.
Oh, and apparently 'Britain First' wasn't said at any time:

Breitbart is not a reliable source. Reliable sources say that multiple eye witnesses have reported him as shouting 'Britain First'.
Also, Breitbart, accusing others of politicising events is absolute rankest hypocrisy.
