Bury sat for Chichester on the interest of the Duke of Richmond, and was a supporter of the Pelhams. After he had succeeded to the peerage he became an important political figure through his association with the Duke of Cumberland.
Horace Walpole describes him as Cumberland’s ‘chief favourite’.
After Henry Fox’s defection to the court in 1762 Albemarle, as Bury now was, became Cumberland’s political agent. He aided Cumberland in his attempt to construct a new Administration, May-July 1765, and on Cumberland’s death was entrusted by the King with the disposal of his papers. Henceforth he adhered to Rockingham and became one of his most trusted advisers. He died 13 Oct. 1772.
