What’s the real reason for the hold-up in the police’s Brexit probe?

Brexiteers are occasionally depicted as being a little paranoid. If you listen to some elite critics of Brexit, you would think that a sizeable chunk of those who voted to Leave are sharing dodgy anti-George Soros memes long into the night. You might think, too, that a few Brexit voters see elite stitch-ups everywhere and never let the truth get in the way of their anti-Brussels prejudices. But if there is a paranoid style in British politics at the moment, it is not being practised by the 17.4million.
