Dr Tiffany Jenkins, author of Keeping Their Marbles, will join new trustees including TV broadcaster and writer Claudia Winkleman, Lord Finkelstein, a Conservative peer who was an adviser to prime minister John Major, the historian and podcaster Tom Holland and the former BBC radio news anchor Martha Kearney for a four-year term. The chair of trustees is George Osborne, the former Conservative chancellor of the exchequer.

In her book Keeping Their Marbles: How the Treasures of the Past Ended up in Museums… and Why They Should Stay There, Jenkins examined the influences behind the high-profile battle to return museum artefacts in an attempt to repair historical wrongs. Her views are at odds with those of another well-known historian and broadcaster, Dr Alice Roberts, who recently met the Greek culture minister, Lina Mendoni, while filming her series on Ancient Greece for Channel 4.
