Returned in 1832 for Lymington, it appears that Stewart may have been the first Member of Parliament from an ethnic minority background. He was born in the West Indies in 1789,
His father’s will made generous provision for Stewart and his other illegitimate children, as well as for numerous friends and dependants. Although the will gave Stewart senior’s trustees the discretionary power to sell his West Indies estates to fund these bequests, his son took possession of estates in Grenada and Demerara (later part of British Guiana), as well as his father’s London residence in the Albany. Stewart was also left his father’s gold watch.
In July 1832 Stewart canvassed Lymington, where he was described as ‘a gentleman of independent and liberal principles’.
At the time of Stewart’s election the press described him variously as a radical,
Although Stewart had pledged to reside in or near Lymington during part of the Parliamentary vacation,
Stewart was re-elected unopposed in 1835, when he declared that he had ‘ever been the uncompromising advocate for every practicable economy in every department of the state’ and that he was in favour of reforming not destroying its institutions. He wished to give relief to Nonconformists without disturbing the security of the Established Church. He did not regret the change of ministry and ‘without entirely approving of the constitution’ of Peel’s administration he had no hesitation in acknowledging his confidence in its principal members. He intended to give them his support and anticipated that their ‘habits of business possessed... in so superior a degree over their predecessors’ meant that their measures would be ‘less crude and better matured’.
Stewart’s party allegiance was confirmed by his votes with the Peel ministry on the speakership, 19 Feb., the address, 26 Feb., and Russell’s motion on the Irish church, 2 Apr. 1835. He was in the minorities for Chandos’s motion on agricultural distress, 25 May, and Poulter’s Sabbath observance bill, 2 June. He made a brief interjection regarding the recorder of Lymington during the debate on the municipal corporations bill, 22 June 1835.
At the 1837 general election Stewart was re-elected at the head of the poll. The press now listed him as a Tory although the 1838 edition of The assembled Commons still referred to him as ‘a commercial gentleman of great respectability, a moderate Whig’.
A silent member for the remainder of his parliamentary career, Stewart generally divided with the Conservatives, although he was a sporadic attender. His committee service appears to have been confined to private bills.
At the nomination in 1841 Stewart was suffering from illness and spoke in such a low voice that he was unable to be heard, but was nonetheless re-elected at the head of the poll.
Seeking re-election in 1847, Stewart defended his conduct on the slave trade and his votes on the sugar question and the corn laws, but was defeated in third place.
Stewart, who although ‘a strict disciplinarian’ was regarded as ‘a liberal and kind-hearted master’,
