Artist who once draped Barbican in brightly coloured fabric says he is humbled by recognition in ArtReview rankings

The Ghanaian artist Ibrahim Mahama has become the first African to be named the most influential figure in the art world in ArtReview magazine’s annual power list.

Mahama, whose work often uses found materials including textile remnants, topped the ranking of the contemporary art world’s most influential people and organisations as chosen by a global judging panel.
