Zamalek chairman Mortada Mansour has launched a lawsuit before the general prosecutor on Tuesday against the Egyptian Football Association (EFA) refereeing committee head Ahmed Wagih and others claiming involvement in what he describes as "biggest corruption case in Egyptian football'.

"I have documents and recordings prove that an international company paid a one million pound bribe -- and offered another -- in the biggest corruption case in Egyptian football," outspoken lawyer and parliament member Mansour claimed in a press conference at the club's headquarters on Tuesday afternoon.

"We will not surrender and if no action is taken before Sunday, I will reveal to the press all the corruption scandal details and all the names involved," he added.

Under Mansour’s guidance, the defending champions Zamalek announced their withdrawal from the Egyptian Premier League in protest at "refereeing mistakes" during their first loss this season on Sunday against Talae El-Geish refereed by Mahmoud El-Banaa.

"Zamalek won't play the Mahalla game [scheduled for Wednesday] until the association sack Wagih and all the members involved in the scandal," added Mansour, revealing he also called the club's committee [he bosses] to an extraordinary meeting on Friday.

The EFA ignored Zamalek's complaint earlier on Monday about the standard of refereeing and backed their committee.

The next few hours will reveal more updates regarding the matter as the title-hungry Zamalek would be exposed to sever punishments if they abandon tomorrow's game.

Zamalek are in sixth place with 13 points, seven behind leaders Dakhlya who have played two extra matches. Meanwhile, their rivals Ahly lie ninth on the league table with nine points.
