Appearing before a parliamentary committee, Dyke said FIFA should publish in full a report into the bidding process for 2018 and 2022 being compiled by American lawyer Michael Garcia.
However, Dyke played down talking of stripping Russia of the 2018 tournament because of political tensions over Ukraine.
Garcia, who has been leading a FIFA ethics committee investigation into allegations of corruption surrounding the award of the 2022 World Cup to the Gulf state, will submit his report in September.
“If Mr Garcia shows that there have been corrupt activities, the whole thing should be reconsidered,” Dyke said.
Dyke said he was convinced that the tournament would not be held in June or July if it was played in Qatar because of the intense heat, with a move to a cooler time of the year like November or December a certainty.
Dyke played down suggestions that Russia could be stripped of the World Cup as a punishment for the downing of a passenger plane over Ukraine last week which Western nations have blamed on separatists backed by Moscow.
“I think there will be a World Cup in Russia,” Dyke told reporters after the hearing.
He had earlier told lawmakers that a decision to move a World Cup should not be based on “one week’s events”.- Reuters
