He was educated at home, and entered the 10th Hussars, as Cornet, in 1819. He entered political life as secretary of Mr. Canning, who had married his maternal aunt, and was so engaged for three years. "Tall and well made, both in grace and figure, a model of manly beauty, quick of eye and action, he was distinguished by his skill in every kind of sport." He inherited a taste for racing, combining with it "a fine sense of honour which made his patronage of the sport a benefit for racing society". On the turf he was most successful. Later he joined the 2nd Life Guards, but in 1828 became M.P. for King's Lynn, which he represented till his death.

He was, "as became his birth, a Whig of the Revolution era". He voted for the Catholic Emancipation Bill, and upheld generally the principles of the Reform Bill. In 1845 he became an active opponent of Sir Robert Peel, and approved of the Corn Laws, taking an active part in organizing the Protectionists as an independent party, and, in 1847, sold his racing stud that he might devote himself to politics. His career is summarized in the D.N.B. at considerable length. He died suddenly, on the 21st Sept. 1848, at the early age of 46, near Welbeck, it was said "from a sudden spasm of the heart", and was buried in the old parish church of Marylebone, the burying-place of his family.
