Tai Shani, a London-based artist who won the Turner Prize in 2019, said this week that she was terminating a book contract with Phaidon, the arts book publisher that has been owned by billionaire art collector Leon Black since 2012.

Shani cited Black’s connections to disgraced financier and convicted sex offender Jeffrey Epstein, including “numerous horrific allegations” about Black and some which have been newly revealed as part of the Department Justice’s recent release of Epstein-related documents.
