The head of the Qatar Museums Authority (QMA) has been named the most powerful figure in the art world.
Sheikha Al-Mayassa bint Hamad bin Khalifa Al-Thani came top of ArtReview magazine's annual Power 100 due to her organisation's "vast purchasing power".
The BBC's arts editor Will Gompertz explained Sheikha Al-Mayassa's rise from number 90 in the Power 100 in 2011 to number one in 2013.
He speculated that Qatar's emergence into the art world "is about creating a knowledge economy".
