Gulnara Karimova was once viewed as a potential successor to her strongman father.
But the daughter of Uzbekistan's President Islam Karimov has seen a spectacular fall from grace.
The Central Asian country of Uzbekistan is considered to be one of the world's most isolated and repressive countries.
It is likely to become increasingly important as Nato prepares to withdraw equipment from neighbouring Afghanistan this year.
Uzbekistan has faced criticism over its human rights record, and now it seems it may have an outspoken human rights campaigner - the President's own daughter.
