Fifa suspends Bin Hammam and Warner after ethics hearing
Fifa has provisionally suspended executive committee members Mohamed Bin Hammam and Jack Warner after a meeting of its ethics committee on Sunday.
Football's governing body will now open a full investigation into allegations that financial incentives were offered to members of the Caribbean Football Union (CFU).
CFU officials Debbie Minguell and Jason Sylvester have also been suspended.
However, no action will be taken against Fifa president Sepp Blatter.
"We are satisfied that there is a case to be answered," said Petrus Damaseb, deputy chairman of the ethics committee.
However, Fifa insists that they are innocent until proven guilty.
If found guilty, they could be expelled from the organisation and banned from all football activity.
Bin Hammam, who was the only candidate due to oppose Blatter in the forthcoming election, until he withdrew in the early hours of Sunday morning, and vice-president Warner were forced to answer charges of bribery over allegations from executive committee member Chuck Blazer in Zurich on Sunday.
It was alleged that they offered bribes at a meeting of the CFU on 10 and 11 May.
A file of evidence claimed bundles of cash of up to $40,000 (£24,200) were handed over to members of the CFU at the meeting in Trinidad.
The payments were allegedly made to secure votes for Bin Hammam in his campaign to challenge Blatter for the presidency.
In turn, Bin Hammam effectively claimed Blatter was aware of some wrongdoing but did not report it, in itself a breach of Fifa's ethics code.
Fifa also confirmed at Sunday's news conference that the presidential election will go ahead as planned on Wednesday.
