Originally Leicestershire yeomen, the Clementses had advanced themselves over several generations through the holding of lucrative revenue offices and parliamentary seats in Ireland. Clements was the grandson of the financial expert and political fixer Nathaniel Clements (1705-77), whose eldest son became the 1st earl of Leitrim in the Irish peerage, and whose youngest son, this Member’s father, succeeded him as Member for county Leitrim and deputy vice-treasurer of Ireland. Nathaniel’s divided inheritance, with the Leitrim electoral interest initially going to the Cavan branch of the family, produced a family conflict over the representation well into the early nineteenth century.
Taking after Henry, Clements voted against Catholic relief, 28 Feb. 1821, and the Catholic peers bill, 30 Apr. 1822. A silent and largely inactive Tory, he divided with the Liverpool administration against tax reductions and lower expenditure, 3, 12 Apr., 18, 27 June 1821, 11 Feb. 1822.
Clements rejoined the army in November 1828, but resigned in June 1830 in order to contest Leitrim against his kinsman at the general election that summer. He was presumably accompanied by his mother’s relation Charles Cobb Beresford, who reported to Archbishop Beresford that ‘the fact is John Clements is quite helpless in matters of business and, if left to himself, I would be very apprehensive either of his committing himself or getting into some [scrape]’. He declined all pledges put to him on the hustings, but, once he had headed the poll, he claimed that he would have voted against the increased Irish stamp and spirit duties had he been in the House.
A radical source commented in 1831 that Clements ‘seldom votes and never speaks - a valuable Member!’
