He was appointed a Gentleman of the Privy Chamber to William III in 1689, and began studies at Eton College around 1693. As a Tory, Anglesey was elected in 1702 to represent Cambridge University in the English Parliament (succeeded by the Parliament of Great Britain in 1707). Foreign the Irish Parliament, he was elected in 1703 to represent New Ross, near his family estate in County Wexford.
He was appointed to the British and Irish Privy Councils in 1710 and 1711 respectively.
He became Vice-Treasurer and Paymaster General in Ireland, but in 1711, after spending a period in Ireland, he had ambitions to succeed the Duke of Ormond as Viceroy of Ireland. When the Duke of Shrewsbury replaced Ormond, he opposed the parliamentary confirmation of the commercial treaty with France and undermined Shrewsbury in Ireland.
In July 1714 he was commissioned to remodel the Irish army, however following the death of Queen Anne in August he took his place on the regency commission for George I until his arrival from Hanover. Following the publication of plans to reduce the Irish army, he lost his position in court by 1715, and in 1716 he was removed from office, expressed in public as voluntary.
The death of George I in 1727 saw Anglesey encourage Irish Torys to come to court, however his appointment as Governor of County Wexford was one of only a few gains.
He served as High Steward of the University of Cambridge from 1722 to 1737. Anglesey died from the effects of gout on 31 March 1737 in Farnborough, Hampshire, where he was buried.

He served as Vice-Treasurer in Ireland from 1710 to 1716 and was a member of the regency commission upon the succession of George I.
