Fifa faces seminal moment after Triesman allegations
Lord Triesman has long promised to lift the lid on what really happened while he was chairman of the failed England 2018 World Cup bid.
On Tuesday, he finally got his chance, using the platform of the culture, media and sport select committee to name four Fifa executives he claims asked for gifts or favours in return for their support - behaviour he says was ethically unacceptable.
In his most explosive allegation, the Labour peer said that, in October 2009, Jack Warner, a Fifa vice-president from Trinidad and Tobago, asked for cash - suggested to be £2.5m - to build a new education centre and offices for the country's football association, a request Lord Triesman rejected immediately.
He also claimed Warner later asked for half a million pounds to buy the TV rights for the 2010 World Cup for Haiti after the country was devastated by an earthquake in January of that year. Warner has denied the allegations.
The former FA chairman went on to allege that another Fifa member, Paraguay's Nicolas Leoz, did not want money for his support but a knighthood.
And Lord Triesman went on.
Two more Fifa members - Ricardo Teixeira of Brazil and Worawi Makudi of Thailand - were also named as behaving inappropriately during conversations about England's bid.
But perhaps the most significant claims came before Lord Triesman even took his seat in committee room 15 at the Palace of Westminster. In a remarkable twist, the Sunday Times - the paper whose undercover investigation last autumn led to two Fifa members being banned for corruption - handed fresh evidence to MPs on the committee.
The paper alleges two more executives - Issa Hayatou of Cameroon and Jacques Anouma of Ivory Coast - were paid $1.5m (£919,000) for supporting Qatar's successful bid for the 2022 World Cup.
These are far more significant as - if true - as they cast serious doubt on the way Qatar shocked the world of football by winning the right to host the World Cup despite ongoing concerns over climate and infrastructure.
All of this, of course, comes on top of Fifa's removal last December of another two members of its executive committee - Reynald Temarri and Amos Adamu - for corruption during the 2018 and 2022 bidding process.
To put all this into context, eight members of the Fifa executive committee at around the time of the vote have now been accused of or found guilty of corruption or breaking Fifa's ethics code. This is a seminal moment for Fifa.
Faced with these latest revelations, Fifa president Sepp Blatter said the governing body would act immediately if presented with evidence of wrongdoing.
Blatter is bidding for a fourth term as president three in three weeks. And while he has not been accused of any wrongdoing, all these claims have come on his watch.
Unless he acts swiftly and decisively, Fifa may soon not have a reputation left to protect.
