Reports in the British media claim that members of the nation's bidding team paid money to officials in exchange for votes, leading to the tournament sponsor's unrestWorld Cup sponsor Sony has called on Fifa to look into allegations of corruption relating to the awarding of the 2022 tournament to Qatar.
Recent reports in the British media suggested Mohamed Bin Hammam, a former president of the Asian Football Confederation, paid up to €3.7 million (£3m) to football officials to drum up support for Qatar's bid.
Those allegations have been strongly denied by Qatar's bid committee, which said that it "upheld the highest standard of ethics and integrity" throughout the process, but Fifa is currently conducting an investigation into the matter, as well as the decision to award Russia the 2018 tournament.
However, further accusations were made in the British press on Sunday and technology giant Sony has become the first sponsor to voice its concerns.
"As a Fifa partner, we expect these allegations to be investigated appropriately," Sony is quoted as saying in a statement to The Sunday Times.
"We continue to expect Fifa to adhere to its principles of integrity, ethics and fair play across all aspects of its operations."
The 2014 tournament gets under way in Brazil on Thursday.
