Artists threaten boycott over Abu Dhabi worker welfare

A group of artists is threatening to withhold work from exhibition in Abu Dhabi's new galleries, over concerns about the welfare of those constructing the buildings.

The authorities are spending billions of dollars on the new museums, which include a Louvre and Guggenheim, and have built special accommodation for the workers.

However the artists are demanding further improvements, as Jonathan Frewin reports from Abu Dhabi.
