Cumming, who became a financial speculator after a period of service with the East India Company, was again returned for Inverness Burghs in 1820. Under the electoral pact between his nephew Sir William Gordon Cumming* and their kinsman Colonel Francis William Grant* it was the latter’s turn to nominate the Member, but in Grant’s absence abroad his representatives decided to retain Cumming in the seat as ‘a firm friend’ of the Liverpool ministry and Lord Melville, its Scottish manager.
Cumming retired from Parliament at the dissolution in 1826. He died a bachelor in May 1834, ‘aged 81’.
