Resignation of Adhaf Souief.
Egyptian novelist Ahdaf Soueif resigned from the board in 2019, citing issues with "corporate sponsorship" by BP as well as the Museum's refusal to repatriate artifacts such as the Parthenon Marbles which she felt should have been repatriated. The resignation was supported by staff members at the British Museum, who were reported by "the Guardian" to "expressed support" for Soueif. In a 2018 article for "the Guardian", Lambert stated that the Elgin Marbles should remain in the museum and opposed their repatriation to the Greek government. 
Former trustees.
The 1753 British Museum Act established a 42 strong Board of Trustees, which included two representatives each of the Sloane, Cotton, and Harley families, elected representatives and the following ex-officio: Archbishop of Canterbury, Lord Chancellor, Speaker of the House of Commons, Lord President of the Council, First Lord of the Treasury, Lord Privy Seal, Lord High Admiral, Lord Steward, Lord Chamberlain, the three Principal Secretaries of State, Bishop of London, Chancellor of the Exchequer, Lord Chief Justice King's Bench, Master of the Rolls, Lord Chief Justice Common Pleas, Attorney General, and Solicitor General.
This rose to 50 by the mid-1800s, including the addition of a trustee appointed by the Crown (1832 British Museum Act) and one representative each from the Towneley, Elgin, and Knight families.
The British Museum Act 1963 reduced the number of trustees to the current 25 and set the time-limit on appointments.
