Greek Olympian triple jumper Voula Papachristou has been expelled from her country’s Olympic team over comments she posted on Twitter which were deemed racist.

Voula Papachristou was due to compete in the London 2012 Games, which officially start this Friday.

But the Hellenic Olympic Committee said her posts mocking African immigrants and expressing support for a far-right party went against the Olympic spirit.

Voula Papachristou has apologized for the “unfortunate and tasteless joke”.

As well as the comment on Sunday referring to the West Nile virus and Africans living in Greece, Voula Papachristou had also reposted a tweet by Ilias Kasidiaris, a politician with the far-right Golden Dawn party, criticizing Prime Minister Antonis Samaras’s stance on immigration.

She had previously retweeted several links to videos promoting the views of Golden Dawn, which won 7% of the vote in Greece’s recent elections, and had directly communicated online with Ilias Kasidiaris.

Ilias Kasidiaris gained notoriety for slapping one left-wing woman politician and throwing water over another, during a heated debate on a television show.

Triple jumper Voula Papachristou has been expelled from Greek's Olympic team over racist comments she posted on Twitter

Voula Papachristou tweeted him on his name day last week: “Many happy years, be always strong and true!!!”

The athlete’s remarks had prompted calls from the public and within the Greek government for her to be thrown out of the team.

The head of the Greek committee, Isidoros Kouvelos, said the 23-year-old had “showed no respect for the basic Olympian value”.

“She made a mistake and in life we pay for our mistakes,” he told Skai TV.

Earlier in the week, Voula Papachristou had responded online, saying “that’s how I am” and that she was not like a stuck CD: “If I make mistakes, I don’t press the replay! I press Play and move on!”

But in a statement on her Facebook page and Twitter on Wednesday, Voula Papachristou said she was “very sorry and ashamed for the negative responses I triggered, since I never wanted to offend anyone, or to encroach human rights”.

She apologized to her friends, family, fellow athletes and the national team, but said it would not have been possible for her to compete if she did not support the values of the Games.

“Therefore, I could never believe in discrimination between human beings and races.”

The Greek committee said she had been “placed outside the Olympic team for statements contrary to the values and ideas of the Olympic movement”.

However, her coach George Pomaski said the punishment had been too harsh and she had already apologized.

“This is a big disappointment not only for her but for her family and for myself, and anyone involved in the Greek team,” he said.

George Pomaski said he had been unable to contact Voula Papachristou for several hours.

Greece is experiencing a sharp rise in racism, with the popularity of right-wing parties such as Golden Dawn soaring.

The government has come under pressure to crack down on racism in all domains, including sport.

The Olympic Charter

The Olympic Charter, established by Baron Pierre de Coubertin the founder of the modern competition, states that: “The practice of sport is a human right.”

Everyone should be able to play sport “without discrimination of any kind and in the Olympic spirit, which requires mutual understanding with a spirit of friendship, solidarity and fair play.”

The spirit of the games is about the power of sport over politics, where perseverance and hard work are paid off with medals; where ordinary people can become national heroes.

This ideology has been expanded over the years. In the words of the London2012 official education programme, Get Set: “The Olympic and Paralympic Games are about much more than sporting excellence.”
