The Sunday Times has obtained secret documents that it alleges are proof that Qatari football official Mohamed Bin Hammam made payments totaling $5 million to football officials in return for their support for the Qatar bid.

According to emails obtained by the Sunday Times and seen by the BBC, it is now clear that Bin Hammam, 65, was lobbying on his country's behalf at least a year before the decision.

The documents also show how Bin Hammam was making payments direct to football officials in Africa to allegedly buy their support for Qatar in the contest.
