Heads of state muscle in on vote
IOC wants to stick to ethics
Whether they are presidents, kings or prime ministers, heads of state have muscled into the inner sanctum of the IOC in recent years, successfully swinging votes for their bids.
When the IOC meets in Copenhagen today week to elect the hosts of the 2016 Summer Olympics, Chicago, Tokyo, Rio de Janeiro and Madrid will bank on senior politicians to be there working the corridors of power.
Until a few years ago heads of state did not make a point of attending the Olympic vote.
However, the ballooning size and budget of the Games and the 2002 Salt Lake City Olympics bribery scandal, where gifts were exchanged for votes, contributed to a change in practice as IOC members were banned from travelling to candidate cities.
In 2005 when the IOC was voting for the 2012 Olympics, then British Prime Minister Tony Blair flew into Singapore to meet dozens of IOC members and actively back London's bid.
French leader Jacques Chirac was also there, though he was holding the bare minimum of meetings, thinking frontrunner Paris had done enough with a good bid.
As has been the case on many an IOC vote, the favourite was left beaten, with London celebrating an unexpected victory largely credited to Blair's successful lobbying.
At the IOC session in Guatemala in 2007 there were two clear frontrunners for the 2014 Winter Games: Austria's Salzburg with a long winter sports tradition and South Korea's Pyeongchang, which had narrowly missed out to Vancouver four years earlier.
Rank outsider Sochi, Russia's Black Sea resort, had technically the weakest bid with almost all of the venues needed to be built from scratch.
The presence of Russian President Vladimir Putin at the session, addressing the IOC members in impeccable English - a first according to his country's reporters - proved decisive as Sochi snatched victory.
The IOC has taken notice of politicians' growing presence and has urged heads of state to attend sessions without upstaging the event itself with long car convoys, large security and an even larger entourage.
"We will treat them according to the protocol. If heads of state want to be present that is their full right," IOC president Jacques Rogge said.
"But we want to contain the activities to what has been agreed by the ethics commission.
"Of course, the IOC is very honoured with the presence of dignitaries. It is also a reassurance that public authorities are behind the bid but it is not a requirement of the IOC."
When the world's top sports officials arrive in Copenhagen, leaders from all four bidders are expected to join them.
Brazilian President Luiz Inacio Lula da Silva and Spanish King Juan Carlos as well as Prime Minister Jose Luis Rodriguez Zapatero will go to Denmark while Tokyo officials are working hard to get new Prime Minister Yukio Hatoyama to fly in.
An appearance by Japanese Emperor Akihito should also not come as a surprise.
Chicago had been holding out for US President Barack Obama, who has spent much of his life in the US city, to travel to the session.
Locked in a domestic healthcare reform battle at home, Chicago officials will instead have the on-site support of First Lady Michelle Obama, a Chicagoan, who has confirmed her attendance.
