Lemon, who had sat previously on the interest of his brother-in-law John Buller of Morval, was left out in 1790, the latter being already engaged to place Lemon’s seat at the disposal of William Beckford.
Lemon voted with opposition in the 1796 Parliament almost as regularly as his brother Sir William, like whom he belonged to the ‘armed neutrality’ of 1797. He may have seceded, for after voting in favour of reform, 26 May 1797, the only minority votes recorded between then and the session of 1800 were against Pitt’s taxes, 4 Jan. 1798, and on Ireland, 22 June 1798. He resumed regular opposition in 1800 and 1801. He voted for Nicholls’s motion of 7 May 1802 thanking the King for the removal of Pitt. He was better disposed to Addington, to whom his friendship with De Dunstanville commended him, and while he supported Calcraft’s motion on the Prince of Wales’s debts, 4 Mar. 1803, he accepted a place on the Admiralty board in January 1804. Fox noted that he had ‘completely gone’, but was not surprised.
When Pitt returned to power, Lemon went into opposition with Addington
between ourselves, though I have the highest regard for Lemon and know his many valuable qualities, he is the strangest politician I ever knew: of politics indeed in the true sense of the word he never treats; but though one of the best tempered men I know in private life, he has the strongest antipathies to men in public situations that extend to almost every public man with the exception only of yourself of whom he always speaks with the greatest affection and esteem.
In 1810 he was listed ‘present opposition’ by the Whigs and his voting conduct confirmed it on all major issues. He voted regularly for sinecure reform, but was absent on Brand’s motion for parliamentary reform, 21 May 1810, and could not be rallied to an extra-parliamentary meeting of Friends of Constitutional Reform in 1811. On 14 May 1811 he said a few words on the proposed interchange of militias. He supported Catholic relief at every opportunity, speaking on behalf of it, 23 Apr. 1812. Lemon died 5 Apr. 1814.
