Leader, like his father, prospered handsomely in business. He was a partner with John Falconer Atlee and James Langdale in a malt distillery at Wandsworth and had a stake in the firm of Pellatt and Green, china, glass and earthenware dealers, of 16 St. Paul’s Churchyard.
In 1824 he divided for repeal of the usury laws, 27 Feb., 8 Apr., as he did again, 8, 17 Feb. 1825. He voted to get rid of the window tax, 2 Mar., and to transfer the duty from beer to malt, 15 Mar. 1824. He divided against military flogging, 15 Mar., and naval impressment, 10 June, and opposed the aliens bill, 23 Mar., 12 Apr. He favoured Scottish judicial reform, 30 Mar., and allowing counsel for defendants in cases of felony to address the jury on the evidence, 6 Apr. He voted in condemnation of the trial of the missionary John Smith, 11 June. He supported an advance of capital to Ireland, 4 May, and reform of her church establishment, 6, 25, 27 May, but he divided with government for the Irish insurrection bill, 14 June. His son recalled that Leader never spoke in the House ‘except to present a petition from his constituents’: he produced one in support of the county courts bill, 14 Apr. 1824.
Leader, whose elder son William was killed, at the age of 24, in a carriage accident in Oxford, 28 Feb. 1826, made a will on 2 Aug. of that year. He left his wife £1,000 and an annuity of £1,500. He had secured to his four daughters £10,000 each by their marriage settlements, and he now bequeathed an additional sum of £10,000 each to three of them, having provided the other with the same amount by bond. Various other legacies to relatives and his executors amounted to some £14,500. He left the residue of his personalty and all his real estate to his surviving son John, who was to receive £1,000 a year until he attained his majority.
The will was brought to him; he attempted to sit up, but was unable; a pen was given to him, and he was lifted up in the bed, but at the very instant he was about to sign the paper, he expired.
PROB 11/1753/167; The Times, 16 Jan. 1828, 14 Jan. 1829; Ann. Reg. (1829), Chron. pp. 8-10.
The will of 1826 was proved under £300,000 on 1 Feb. 1828, but this probate was revoked by interlocutory decree, 13 Jan. 1829, when judgment was given in favour of the second will and its annexed bonds as representing the clear intention of the deceased. It too was proved under £300,000 on 24 Mar. 1829. The personalty amounted to almost £200,000, in addition to real estate worth about £100,000.
