John Doyle, After attaining his majority, he was returned on his father's interest for
Scarborough in 1818. However, in the summer of 1819, he began to break with his family's Tory politics, and signalised his conversion to the Whigs by joining
Brooks' Club on 3 December. When Parliament was dissolved in 1820, Normanby was in
Florence, Italy, to which he was a regular visitor. His brother
Charles kept up the family interest with the Scarborough corporation, and Normanby was returned in absentia in March, despite being politically at odds with his father. This state of affairs was not to last long: in May, Normanby was compelled to
take the Chiltern Hundreds by Lord Mulgrave, to vacate the seat for Mulgrave's brother
Edmund. His standing as a former Tory minister's son made Normanby valuable to the Whigs, and they hoped to return him to Parliament in another seat. An attempt was made to have him put in at
St Ives at a by-election in 1821, but support proved to be lacking, and Normanby withdrew without contesting the seat. The illness and death of
William Plumer in the beginning of 1822 allowed him to take his seat in February for
Higham Ferrers, a pocket borough of the Whig grandee
Earl Fitzwilliam. He made a considerable reputation by political pamphlets and by his speeches in the house. He was returned for
Malton at the general election of 1826, another one of Fitzwilliam's boroughs. He was already known as a writer of romantic tales,
The English in Italy (1825); in the same year he made his appearance as a novelist with
Matilda, and in 1828 he produced another novel,
Yes and No. He declined to be nominated again for Malton in 1830, anticipating the imminent death of his father, and was thus out of Parliament when
Lord Grey formed a government in November 1830. Normanby hoped for employment by the foreign office, but none was forthcoming. Through
Lord Durham, Normanby solicited a
writ in acceleration from Grey in early 1831, which would have brought him up to the House of Lords before his father's death; but Normanby succeeded to the Earldom of Mulgrave on his father's death in April, rendering it moot. , In 1832, Mulgrave was sent out as
Governor of Jamaica and was afterwards appointed
Lord Lieutenant of Ireland (1835–1839). On his visit to
Wexford in 1836 he heard a Congratulatory Address in the ancient
Forth and Bargy dialect, then already on the point of becoming extinct. He was created
Marquess of Normanby on 25 June 1838, and held successively the offices of
colonial secretary and
home secretary in the last years of
Lord Melbourne's ministry. While Colonial Secretary, he wrote a letter of instructions to
William Hobson, in which the government's policy for the
sovereignty of
New Zealand was set out. ==Diplomatic career==
