Who has another business? I assume you are talking about Parish? If so, he sold his business last year, made a tidy profit and continued as CEO, although no idea if he's still doing it*. But the tidy profit was around the £50 million mark (IRO) and not the billions (as a co-owner) Palace fans seem to think one of their four musketeers is worth.
* Just read he's stepping down at the end of the year.
Sorry no, I meant Freedman
