ZURICH (AFP) World footballs governing body FIFA said on Monday that it was investigating member associations as well as senior officials over allegations of votes being sold in the World Cup 2018 bidding race. FIFA said in a statement that it had opened proceedings against two members of the FIFA Executive Committee to ascertain whether they have violated the FIFA Code of Ethics, and will consider provisional measures if necessary. Investigations are also ongoing in relation to other FIFA officials who may have been involved in the issue in question, it added, a day after FIFA President Sepp Blatter pledged an in-depth investigation. A British newspaper reported on Sunday that Nigerian and Oceanian members of its executive committee had offered to sell their votes in the bidding race for the 2018 World Cup to undercover journalists posing as lobbyists. However FIFA on Monday also cautioned that any alleged agreements between member associations would be a clear violation of the bidding rules for the World Cup and its Code of Ethics. Therefore, an investigation has also been opened into the member associations in question as well as their Bid Committees, FIFA said in the statement. The governing body did not specify which countries could be under scrutiny. The nations in the running to host the 2018 World Cup are England, Russia, Spain-Portugal and Netherlands-Belgium. For 2022, the contenders are Qatar, Australia, the United States, Japan and South Korea. Last Friday, US Soccer withdrew its bid to host the 2018 World Cup to focus on the 2022 event, leaving an all European field competing for 2018, while England in turn withdrew from the 2022 race. FIFA is due to announce on December 2 which countries will host both events. The British newspaper The Sunday Times said six senior officials, past and present, had told reporters that paying bribes offered the best chance of landing footballs showcase tournament. It also alleged that Amos Adamu, a Nigerian member of FIFAs executive committee, asked its undercover journalists for 800,000 dollars (570,000 euros) to endorse one of the bid candidates. It filmed him meeting with the journalists posing as lobbyists for a United States business consortium, in which he apparently offered a guarantee to vote for the US bid in the 2018 event in return for cash. The report also alleged Reynald Temarii, a FIFA vice-president and president of the Oceania Football Confederation, sought three million New Zealand dollars (1.6 million euros, 2.3 million US dollars) for a sports academy. He allegedly boasted to undercover reporters that supporters of two bid committees had already offered Oceania money to swing his vote. Temarii, from Tahiti, on Monday welcomed a full and thorough investigation so that all the facts can be heard, the Auckland-based Oceania Football Confederation said in a statement. Adamu, a controversial figure who wields major influence over Nigerian football, is also president of the West African Football Union. He has not responded to phone calls since the allegations emerged. Musa Amadu, the acting secretary general of the Nigeria Football Federation, declined to comment in detail, saying we just have to wait for the outcome of this investigation before we can issue a statement on the matter. FIFAs executive committee was alreday scheduled to meet on October 28 and 29 in Zurich to settle various items on the 2018 and 2022 bids, including the final voting process to select the hosts.
