He was returned as a Member of the Irish House of Commons for County Roscommon in 1798, vacating the seat in the following year when he succeeded his father as Earl of Kingston. He subsequently briefly entered the Irish House of Lords. He was created Baron Kingston in the Peerage of the United Kingdom in 1821, thus giving him and his descendants an automatic seat in the British House of Lords.
