In 1761 Hamilton was nominated with Edward Harvey on the Browne interest at Midhurst which had been offered to the court. Two candidates were also put forward on the interest of Sir William Peere Williams, but a compromise was arranged: each side was to nominate one candidate and provide £1,000 to help to bring in the others elsewhere. It was suggested that Hamilton should go to Leominster but he refused to leave Midhurst, and Lord Waldegrave wrote to Newcastle, 22 May 1761: ‘Mr. Harvey gave way to Mr. Hamilton, not because Hamilton had better pretensions, but because Harvey had greater regard to the convenience of his friends.’
There is no record of his having spoken in the House. He was described in Bute’s list of December 1761 as ‘pro’, and appears in Henry Fox’s list of Members favourable to the peace preliminaries.
In April 1763 Hamilton wrote to Charles Jenkinson asking for the embassy at Naples, in case of a vacancy, ‘on account of Mrs. Hamilton’s ill-health and my own situation’.
He died 6 Apr. 1803.
