Nonsense, I am not clutching at straws at all. Merely pointing out that before someone is caught out, they are not serial offenders are they? Otherwise you wouldn't be describing the PM and Owen Patterson because we wouldn't know about it!
Keir Starmer has been caught out lying about Angela Rayner being at the party (and is being investigated by the Police for other matters), an £18,000 advance, tickets to a football match, tickets to a different football match and some minor hospitality that he should have declared but didn't. That is half a dozen things, how many make a serial offender? I suppose for murders it is around 3 or 4 to be a serial killer?
You are just a Labour supporter so happy to believe any nonsense they come out with, and always believe that they are making honest mistakes, whereas you would never believe a Tory would make an honest mistake. You are simply blinkered.
