I'm not saying he should be.If it is provable that Johnson used his position to funnel money,and access to a friend of his then he should face the consequences for it.
Johnson was not, and is not, above the law.
But, again, I must ask for greater honesty from you. Your chief interest in 'outing corruption', as you allege may be involved (?) .. is to attack a political adversary. You know it. I know it.
So tell me why you haven't thought it at all significant to wonder at the timing of all this ... so-called 'damning facts' about Boris, emerging ONLY after A DECADE ???
We're supposed to ignore that, are we, not find anything significant, or 'telling', about such an inexplicable delay ? Pull the other one !!
If you're interested in justice for its own sake, Noir, then entertain the idea that all this comes down to calculated smears, timed for maximum political advantage.
Or, if you're instead only interested in bashing Boris, then, ignore that to the best of your ability (as you clearly prefer to), and 'learn nothing' from the fact of that baffling delay.
