Lloyd’s father represented King’s County in the Irish parliament and he himself was returned for it in 1807. This was with the decisive support of his brother-in-law Lord Rosse, into whose shoes he stepped, and with the countenance of government. He was expected to support them, provided they did not alienate Rosse; but he could not be counted on to attend. ‘Indispensable business’ detained him in Ireland until at least March 1808 and then the chief secretary appealed to Rosse for Lloyd’s attendance ‘towards the close of the session’.
Noting his ‘faint support’, the government feared that he might desert them like his colleague Bernard in 1813, when Lloyd voted for Catholic claims on 2 Mar. and 24 May. They hoped to humour this ‘lukewarm and discontented friend’ by attending to a patronage request. He was in the minority against the expulsion of Lord Cochrane, 5 July 1814, and again on Catholic relief, 9 May 1817, but voted with government in critical divisions, 8 May 1815, 6 and 24 May 1816 and 7 and 25 Feb. 1817. The chief secretary regarded him in June 1817 as a friend of ministers.
