FIFA presidential candidate Mohamed Bin Hammam and vice-president Jack Warner have both been charged with bribery in the most serious corruption crisis to hit the world governing body.
The pair will face FIFA's ethics committee on Sunday where they will face long bans if the allegations - made by fellow executive committee member Chuck Blazer - are proved. Both have denied any wrongdoing.
Sepp Blatter and Bin Hammam were due to stand in the presidential election on Wednesday and the Qatari has declared the charge is a tactic by Blatter in an attempt to boost his chances.
Damian Collins, the MP who named two other FIFA members in Parliament as allegedly receiving bribes from Qatar's 2022 World Cup bid, said FIFA should now abandon the election.
