Kingsborough, a man ‘of a retiring and studious disposition’, had been returned unopposed for county Cork in 1818 on the combined interest of the 3rd Earl of Shannon, a recent convert to the Whigs, and his father ‘Big George’, 3rd Earl of Kingston, who subsequently rallied to the Liverpool ministry.
At the 1826 dissolution Kingsborough retired in favour of his younger brother Robert, citing ‘ill health’; the local press surmised that he ‘prefers the calm pursuits of literature to the troublesome career of a legislator’.
