Stewart Mackenzie’s father, a naval officer, had received the Wigtownshire estate of Glasserton from his father, the 6th earl of Galloway, in 1763, and was Member for the county from 1768 to 1784, when, as a staunch Pittite, he received the sinecure place of receiver-general of the land tax in Scotland. He died in March 1795 and was followed to the grave three months later by his eldest son Keith Stewart, a midshipman on the Queen Charlotte, who ‘fell into the sea and was drowned’ while watching the ship’s carpenter repairing damage sustained in the action off Port L’Orient.
At a county meeting, 1 May 1820, Stewart Mackenzie moved resolutions for an extension of the bounties granted to Scottish fisheries.
Stewart’s parliamentary career begins at a very momentous period ... Bid him to beware! Tell him to steer clear of faction. I admonish him as a sincere friend thoroughly to sift that portentous bill ... and not to be led into an approbation of all its parts by the clamours of the mob.

Repudiating Gairloch’s subsequent reproach that he had not acted quite honestly, Stewart Mackenzie insisted that his supposed ‘information as to my being opposed to reform at any time is quite erroneous. It is true I object to universal suffrage and ballot, but a reformer I have ever been’.
He voted for the second reading of the reintroduced English reform bill, 6 July, and was a general but silent supporter of its details, though he was in the minority for the disfranchisement of Saltash, 26 July 1831, when ministers did not press the issue. He voted for the third reading, 19 Sept., and passage of the measure, 21 Sept. He divided against censuring the Irish administration for interfering in the Dublin election, 23 Aug. On 1 Sept. he secured production of a copy of the report on public charities. Next day he wrote to his wife that he hoped to improve the condition of their Lewis tenantry ‘and not squander the produce of their industry on the expensive luxuries and debaucheries of a distant capital’.
Stewart Mackenzie relished Macaulay’s bravura speech of 16 Dec. 1831 in support of the second reading of the revised English reform bill, for which he duly voted the following day. In a desperate bid to solve his worsening dental problems, he evidently had some of his teeth extracted and false ones made; it did little good, and he was still being tortured over a year later.
At the general election in December 1832, when he replaced Macaulay at the board of control, Stewart Mackenzie easily defeated a Conservative for the Ross and Cromarty seat. He won a narrower victory in 1835, after privately trying to convince a young kinsman who believed he was ‘not desirous to preserve the great institutions of this country’, that to ‘reform, repair and amend what is amiss and with caution to remove defects when glaring ... is the duty of every well wisher to ... [their] continuance’.
