Ponsonby, who had joined Brooks’s, sponsored by Lord William Russell*, 7 June 1806, had unsuccessfully attempted to re-enter Parliament for county Cork in 1818 with the assistance of his brother-in-law Earl Grey and the 6th duke of Devonshire.
At the 1830 general election he was returned for Youghal after a brief contest.
Ponsonby voted for the second reading of the revised reform bill, 17 Dec. 1831, was a majority teller for going into committee on it, 20 Feb. 1832, and again gave steady support to its details. He voted for the third reading, 22 Mar., and for the address calling on the king to appoint only ministers who would carry reform unimpaired, 10 May. He voted for the second reading of the Irish bill, 25 May, against an increase in the Scottish county representation, 1 June, and an amendment to prevent the dismemberment of Perthshire, 15 June. He divided for the Vestry Act amendment bill, 23 Jan. He voted with government on the Russian-Dutch loan, 26 Jan., 12, 16, 20 July, and relations with Portugal, 9 Feb. In a heated exchange with Hunt, 2 Apr., he denied that as chairman of the mutiny bill committee he had given an assurance that it would contain no clause relating to corporal punishment. He complained that insufficient notice had been given to his family and those ‘with an interest’ in the King’s County assizes bill, 18 Apr., condemned the transfer of the assizes from Phillipstown to Tullamore, which had already been rejected by the Irish Parliament and would ‘totally ruin an already poor town’, and moved for a six month postponement but declined to divide, 23 May. He denied that his opposition was ‘influenced by private considerations’, 30 May, and was a teller for the minority of eight against the bill, which he contended violated Acts of 1570 and 1692, 1 June. He voted for the Liverpool disfranchisement bill, 23 May, and coroners’ inquests to be made public, 20 June. He divided for the Irish tithes bill, 13 July, 1 Aug., and defended a military presence at an anti-tithes meeting at Blarney, county Cork, where the troops ‘were merely at their station, the garrison being there’, 2 Aug. 1832.
At the 1832 general election he abandoned Youghal, where it was anticipated that he would be ‘turned out’ by a Repealer, and offered unsuccessfully for Dublin University, rejecting Protestant assertions that he and his Liberal partner were ‘foes’ of the established church, which he argued required reform to ‘conserve it’, and stressing his opposition to repeal.
