Lewis’s long political career, which earned for him locally the affectionate title of the ‘Old Burgess’, was marked by stalwart support of Administration, regular parliamentary attendance, and steady opposition to the ambitions of the Harley family in Radnor. On 11 July 1758 he wrote to Newcastle
The election of 1754 was uncontested, but new difficulties arose in 1761. Chase Price, whose father had opposed Lewis for some forty years,
Carnarvon, however, realized that it might prove impossible for him to stop the opposition in the borough—‘The canvass has begun absolutely against my advice’, he wrote to Bute on 2 Mar., ‘[I] doubt much being able to stop it.’ And next: ‘I have done all I can towards stopping the opposition in the borough of Radnor but find it impracticable; but I shall act in it consistent to the treaty.’ It was Chase Price who continued the contest. Lord Powis wrote to Carnarvon, 2 Mar.: ‘In support and execution of the treaty, your Lordship will find it absolutely necessary to repeat your commands to Mr. Price of Knighton and his family, in favour of Mr. Lewis; which will be obeyed by them (though perhaps with reluctance) undoubtedly.’
The gentleman who now very accidentally serves, totally a stranger to both town and country, owes it entirely to the inattention of the borough, in respect of the stamp duties, which advantage being taken of laid me under a necessity for the preservation of my friends to give way to at that time.
Add. 32987, f. 280.
Lewis’s parliamentary career was over, but his interest in Radnorship politics continued, and he was determined to regain the borough for his nephew, John Lewis. For this purpose the retention of the stewardship was essential and when, in 1765, his rival Oxford applied to Rockingham for this office, Lewis hastened to protest to Newcastle that to take it from his brother would be ‘a very sensible mark upon me likewise, who for 47 years have served in Parliament upon my own expense and interest ... never varying but constant in the support of his Majesty’s and the Whig interest’.
Newcastle’s intervention gained Lewis a reprieve; while in the autumn of 1766 Chase Price’s scheme for the stewardship was defeated by Chatham’s unwillingness to let the first lord of the Treasury engage in it. But when on 18 Jan. 1768 Henry Lewis died, Lord Oxford was appointed to this vital office, a mere seven weeks before the general election.
In the county Oxford’s having declared for Gwynne sufficed to make Lewis support his own former rival Chase Price against him. Nor would he admit defeat in the borough, where in 1768 and 1774 his nephew John Lewis, having the returning officer on his side, was declared elected, only to be unseated on petition. New Radnor had become a pocket borough of the Harleys.
Thomas Lewis died 5 Apr. 1777. The inscription on his monument in Old Radnor church reads: ‘He was blessed with a clear understanding and sound judgment, which being accompanied with an habitual elegance of manners, rendered his conversation at once pleasing and instructive.’ The verdict of Chase Price
This man is the only man in Wales who, without any other merit than a single vote in Parliament, has accumulated an ample fortune; it was said of him that he was never even whimsical; he lived in those fortunate times when feeling ran high, when an individual Member of Parliament was of very great consequence; he saw his ground and kept it—and at the same time showed his understanding; in every other part of his character a rascal of the first water ... In private life he is avaricious, abject, and oppressive; his house is the scene of the meanest economy; and his temper and disposition of the lowest revenge.
I write this gentleman’s character upon a Sunday morning; I would not be supposed capable of telling an untruth at any time, much less upon such a day. It is fortunate for any one to call him an enemy and it has been my good fortune to do it from my cradle.
