Aldama set to divide opinion
Yamile Aldama will be aiming to win her first World Championship medal for Great Britain in the triple jump this morning. If she can pull it off - and it's a long shot considering she didn't even start training until the spring - then expect her achievement to spark another debate about sporting flags of convenience.
Aldama was born in Cuba and won her only silver medal at these championships for her country of origin back in 1999. But she has also competed for Sudan in the Athens Olympics in 2004.
Now she is in Korea as part of the British team having finally got clearance from the International Association of Athletics Federations (IAAF) at the start of August.
For Aldama it is the end of a long and extraordinary journey which began when she met and fell in love with her Scottish husband, Andrew Dodds, while he was studying in Havana. The pair married and moved to Wembley, north London in 2001.
But her attempts to compete for Britain were first thwarted by the Cuban authorities who were angry at her defection having invested so much in her development.
Then her life was turned upside down when Dodds was jailed for 15 years for trafficking £11million worth of heroin in 2002. She says she had no idea her husband was leading this double life and was left with a young child on her own in a strange country. She expected to be deported but in the end she was allowed to stay.
Unable to compete for Britain or Cuba she ended up taking up the flag of Sudan, who fast tracked athletes looking to compete on the international stage. She last represented them at the World Indoor Championships in March 2010.
By then Dodds had been released and, remarkably, they are back together. They have a baby son, Diego, who had his first birthday yesterday. She says they are in love and that she has never been happier.
With her family life settled once again Aldama received her British passport 18 months allowing her finally to compete for a country she has called home for the last 10 years.
It is one of sport's most amazing stories but while she can genuinely lay claim to feel British, having spent so many difficult years in the UK, there will still be those who feel she shouldn't be wearing the team's red, white and blue colours this afternoon.
The so-called plastic Brits debate focuses on Aldama and two other members of the squad here - long jumper Shara Proctor who was born in the British overseas territory of Anguilla and Tiffany Offili-Porter, who has dual American and British nationality.
Proctor failed to make the final of the long jump while Offili-Porter competes in Friday's heats of the 100 metres hurdles. You may recall Offili-Porter caused consternation back in July when she tweeted on Independence Day that she wished she was "in the States" adding that she was definitely there in spirit.
British head coach Charles Van Comennee says he has no problems with selecting any foreign born Brits - as long as they are good enough. Well, how could Britain's Dutch born coach credibly raise any objections?
However, it does raise the question as to whether some athletes are nailing their colours to Britain's mast to try and cash in on the London 2012 experience.
This is hardly new for Olympic hosts and there are other sports who have naturalised foreign born nationals in time to boost their teams before next summer.
For example, British wrestling is now funding five Ukrainian and Bulgarian wrestlers in the hope they might deliver medals for Team GB in a sport where we have no tradition of competing.
But the Greeks did it before Athens 2004, as did the Australians before Sydney in 2000. The Australian pole vaulter Tatiana Grigorieva is one example which springs to mind. Born in Leningrad but naturalised in time for the Millennium Games, she won silver for her adopted country. She still lives there incidentally.
Between now and 2012 there are likely to be many more stories like this. And it is not just in the Olympic sports where this is happening.
Take England's rugby squad for the World Cup. Five of the 30 are foreign born - Matt Stevens, Manu Tuilagi, Dylan Hartley, Alex Corbisiero and Shontayne Hape.
Aldama is competing for a third nation at this year's championships
It's the same in cricket - Andrew Strauss, Kevin Pietersen, Jonathan Trott, Jade Dernbach and Craig Kieswetter were all born in South Africa. Eoin Morgan is Irish.
English football is different. Although the team have had two foreign coaches in the last 10 years, it's difficult to think of any one player who wasn't born in England playing in Fabio Capello's squad. In recent times only Owen Hargreaves, Manchester City's new recruit, was born overseas, in Canada. But his parents are British.
Arsenal's £10million signing Mikel Arteta is Spanish but could play for England. So far that hasn't come to anything.
International sport is a highly paid, competitive professional world. Should sportsmen and women be denied the opportunity of competing on the highest stage and earning a living just because they aren't born in a particular country but are given the opportunity to represent that nation?
Clearly it would be ridiculous if foreigners start wrapping themselves in the Union Jack and weeping every time the band plays God Save the Queen.
But as a nation we are clearly benefiting from the freedom to select overseas born talent. Did anyone who loves English cricket stop to think about whether the presence of so many South Africans in the team when they were celebrating becoming the number one Test team in the world last month or beating Australia in their own back yard in the winter? If England win the Rugby World Cup in New Zealand, will it feel diminished for England supporters? The truth is we are all in denial when it suits us.
The question is whether the presence of all these foreign competitors is in any way reducing the opportunities for home grown talent or distorting the system for developing British sportsmen and women. If that is the case then the governing bodies need to tread carefully.
Yet most put the counter argument that the Premier League is so fond of using - that the presence of foreign stars helps improve the quality of home grown competitors because it raises the quality threshold. The plight of the England football team suggests that is a myth.
Clearly many of you will feel something special in sport is being lost in the rush to recruit foreigners into British sports teams.
But after what she's been through few can begrudge Aldama the chance to wrap herself in the flag of her adopted country if she wins a medal today.
