Somerset House donor married to oligarch quits board

Exclusive: Maria Adonyeva, who gave arts centre at least 380,000, also steps down as Tate patron

The wife of a Russian businessman who at one stage pleaded guilty to defrauding the Kazakh government out of $4m (3m) has stepped down as a patron of the Tate and from a prestigious advisory board at Somerset House, where she was a major donor.

Maria Adonyeva, who has a London-based charitable foundation and has been pictured as recently as 2018 on her husband's yacht with close friends, including the actor Melanie Griffith, has given at least 380,000 in the past two years to Somerset House, where she sat on the arts centre's development advisory board.
