On 13 Feb. 1789 Clifden took his father’s seat in the Irish House of Lords, after six years as Member for county Kilkenny, where the family estates lay. He had ‘no interest’ in England and owed his seat at Westminster to his marriage to the Duke of Marlborough’s daughter, coming in on the duke’s interest a year after it. In Dublin he had acted with the Whig opposition; at Westminster he supported Pitt’s administration. In his only known speech, he moved the address, in favour of the prosecution of war with France, 21 Jan. 1794. On 24 Nov. 1795 he was a government teller. On 18 Feb. 1797 he wrote to Pitt announcing his departure for Ireland, where he felt he could be of more service ‘in support of the government and in defence of the country’. He added, ‘I am sorry to leave the House of Commons at such a time, but I hope and believe the want of a single vote will not be felt’. On 23 May he wrote to Charles Abbot from Dublin that he was proceeding with his cavalry corps to pacify county Kilkenny; if the French invaded, he would vacate his seat at Westminster, which might then be Abbot’s.
That year, so Clifden later assured Pitt, he risked his life and spent his money to suppress the Irish rebellion. His reward was to be the perpetualization of the Irish sinecure he held during pleasure; (it was commuted into £200 p.a. and abolished in his lifetime). He further claimed that ‘no man in England’ supported the Union ‘more earnestly’: in token of which he turned out three hostile Members sitting for his two Irish boroughs.
