There aren't that many people who make >10M quid from selling a company they were a co-founder of without some skeletons in their closets... and it's usually taxes. Paying taxes becomes a little more optional if you've got money apparently.
I don't know how fair that is - or put it another way, it lets him off the hook a bit (as it implies he's no worse than anyone else who has made that much money). But lots of people do set up companies without doing anything as dodgy as this seems.
And this dodgy fuck is our chancellor.
They’re all on the take these people.
