I’m not a fan of his, I find him annoying in the extreme but this is very old news. And having a criminal record does not mean you are always or still, a criminal. He did his time, has never denied his past and has been on the straight and narrow for twenty years. As far as we are aware he is now an honest, working man.
It’s pretty impressive he has rebuilt his life considering how high recidivism rates are in the UK It is very hard for prisoners to get any sort of employment once released because of attitudes like ‘ he is a criminal because he has a criminal record’, so for him to get work in the first place was good going, let alone achieve the level of success he has.
