Spalding’s father invested his mercantile wealth in property in Kirkcudbright, which he increased by marriage to an heiress. Spalding, who received his commercial education from Thomas Sword of Pancras Lane, London, went out to Madras as a writer in 1781 and returned to Scotland eight years later, probably because of ill health.
Spalding, a silent Member, appears in no surviving minority list. On 4 Jan. 1798 he voted for Pitt’s assessed taxes bill and seems to have supported both Pitt and Addington, though by 1802 his patron was ‘decidedly hostile to Mr Dundas’. On 11 Feb. 1803 he was teller for the discharge of the Kirkcudbright petition. He died at Hill Street, Berkeley Square, 26 Aug. 1815, aged 52.
