Poole was a faithful follower of the Pelhams, to whom he owed his seat and much of his livelihood. In 1754 he was in receipt of a secret service pension of £300 per annum, and his office of deputy paymaster in Minorca, since 1747 incompatible with a seat in Parliament, was held in trust for him by his son Henry; but the office disappeared with the loss of the island in May 1756. In November Poole was paid an additional £200 from secret service funds, but at the beginning of 1757 Lady Poole wrote to Newcastle from Lewes of ‘the utter impossibility without some assistance of our living here’.
A week or so later Poole fell ill, and died on 15 Feb. 1763 at the age of 81.
