A major World Cup sponsor has urged Fifa to carry out an "appropriate investigation" into the bidding process which saw Qatar awarded football's elite tournament in 2022, according to reports.
Japanese electronics firm Sony became the first big sponsor to call on football's governing body to investigate the bid.
The company's call comes as The Sunday Times (£) published further secret documents, which they claim shows Qatar's top football chief exploited the country's wealth to win votes for its World Cup bid.
Former Fifa vice-president Mohamed bin Hammam arranged meetings and favours with the Qatari government and royal family for key World Cup voters in the months before the ballot, the newspaper claims.
