The two Fifa executive committee members accused of being willing to accept bribes in order for their vote in the bidding process for the 2018 and 2022 World Cup finals have been suspended from all footballing activity by the sport's governing body.

The Sunday Times claimed on Sunday that Nigeria's Amos Adamu and Tahiti's Reynald Temarii had indicated their willingness to back the United States for the 2018 tournament in return for money.

Both men offered statements to Fifa's ethics committee on Wednesday, with the Sunday Times providing the investigators with their video evidence.

Claudio Sulser, chairman of the committee, expected the investigation to be completed within a month - meaning it would be completed before the decision is made on who will host the two tournaments.

"This is a sad day for football and for Fifa. I have read a lot over the past few days, please bear in mind that everyone who works in this building are trying to do everything we can for the greater good.," he said.

"We have also taken measures concerning other members of different federations. Slim Aloulou, Amadou Diakite, Ahongalu Fusimalohi and Ismael Bhamjee, who are not members of the executive committee, have also been suspended.

"There are no proceedings open against other executive committee members."

Jerome Valcke, the Fifa secretary general, said the investigation into alleged corruption of two people is not a sign of endemic problems with the voting system or the decision to award the 2018 and 2022 World Cups at the same time.

"The process for 2018 and 2022 has been perfectly well organised. the committee have in the past sent information and letters to bidders There is no discussion about a postponement of the decision on December 2 or awarding these two World Cups together," he said.

"We are not talking about the process, we had a clear and transparent process. If someone has done something wrong it is up to the ethics committee to decide."
