Drummond, a nephew of the London banker Robert Drummond of Cadland, Hampshire, had prospered in the service of the East India Company in China, and had come in for Perthshire in 1812 under the aegis of his father-in-law the duke of Atholl.
Anticipating the restoration of the family peerage by reversal of the attainder of 1746, a campaign to substitute the 10th earl of Murray’s son John Stuart for Drummond was under way in Perthshire by the summer of 1823, and he was replaced there in March 1824 by another ministerialist, Sir George Murray. His succession as 6th viscount was acknowledged in June, and he took his seat in the Lords as a Scottish representative peer, 6 June 1825.
