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...
It's pretty dreadful reading really. Is it an ego contest? Because Parish has plenty of that. How many times do you see Chairman getting rid of managers over popularity ratings between the two? Hope to God it nevers happens at our place.
