Clarendon was elected to Parliament for Brecon in 1869, a seat he retained until the following year, when he succeeded his father in the earldom and took his seat in the House of Lords. In 1895 he was appointed a Lord-in-waiting in the Unionist administration of Lord Salisbury, a position he held until 1900, when he was promoted to Lord Chamberlain of the Household and admitted to the Privy Council. He retained this office also when Arthur Balfour became Prime Minister in 1902. The government fell in December 1905 and Clarendon was never to return to office.
Apart from his political career Lord Clarendon joined the Hertfordshire Yeomanry as a Troop Quartermaster in 1868, and was commissioned as a Cornet the following year. He was promoted captain in 1872 and to command the regiment in 1879 with the rank of lieutenant-colonel. He was the regiment's longest-serving commanding officer, continuing in the position until 1901 and afterwards becoming its Honorary Colonel in 1908.[2][3] He was also Lord-Lieutenant of Hertfordshire from 1893 to 1914.
Sporting career
Clarendon made one known appearance in first-class cricket for Cambridge University in 1865.[4] He was a right-handed batsman and a roundarm fast bowler. Four of his uncles James, Edward, Robert and Francis Grimston all played first-class cricket, as did his cousin Walter Grimston. Between 1890 and 1896, Lord Clarendon was a member of the Football Committee at West Hertfordshire Sports Club, chairing some of the meetings. During this period the club won three Herts Senior Cups in four years, not entering it in the other year. This football team was later to become known as Watford Football Club.[5]
