It was... Rebekah Vardy's account
There are two situations here. Either that Toad faced prick has somehow got hold of a genuine internal document in which people who work at Coutts call him those things, and that is quite funny. Or he has written that himself and called himself those things which, let's face it, is funnier.
Oh, or somebody has (presumably) sold him a fake document calling him those things, which he is now outragedly hawking to whoever will listen.
Either way it's hilarious.
