He wanted more control but couldn't get it, hardly someone trying to sell to help.Sounds like Textor has been trying to sell for a while because he can't buy more shares (as @ThePaddy says), and not just because of the UEFA issue.
Quotes from Textor, after the hearing:
‘Look, all of the UK knows that I don’t have decisive influence over Palace. It was a good meeting. They listened and we'll see what happens. I wouldn't be trying to sell (this stake) if I did.’
‘We are trying to help separate it and sell. We wanted to buy but it’s become clear that isn’t going to happen and so we’re trying to help Palace and the situation with UEFA. That’s about all I can say.’
