The delay in raising him to the peerage was due to the hostility of George II, who resented Henley's former support of the Prince of Wales's faction, known as the Leicester House party; and it was in order that he might preside as Lord High Steward at the trial of the Earl Ferrers for murder in 1760 that he then received his patent. He resigned from his position in 1767 and died at his residence in Hampshire on 14 January 1772.
