Greek triple jumper Voula Papachristou has been expelled from her country's Olympic team after posting a racially-insensitive tweet on July 22. She tweets(translated from Greek to English), "With so many Africans in Greece .. At least the mosquitoes ofWest Nile .. will eat homemade food!"
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.
Papachristou has apologised for the "unfortunate and tasteless joke".
