Sebright disclaimed connection with a party, but generally acted with the more advanced Whigs. He was a strong advocate of economy in administration, of the abolition of sinecures and unnecessary offices, and of the reduction of indirect taxation. He was in principle a free-trader. On 5 April 1821 he seconded Lord Cranborne's motion for an inquiry into the game laws, and supported subsequent bills for their amendment. In 1826 he attributed the increase of crime chiefly to their influence. In 1824, and again in 1828, he spoke in favour of the repeal of the usury laws, and he ‘detested monopolies of all kinds.’ As a practical agriculturist, owning land in three counties, Sebright gave his opinion against any allotments larger than kitchen-gardens, but was willing to try an experiment on a larger scale. When, on 1 March 1831, Lord John Russell moved for leave to bring in the first Reform Bill, Sebright, as an independent member, seconded the motion; and supported this and the succeeding reform bills. On 17 December 1832 he was returned for Hertfordshire, at the head of the poll, to the first reformed parliament, but retired at its close.
Death and legacy
He died on 15 April 1846 at Turnham Green and was buried at Flamstead. A portrait of him was engraved by S. Reynolds from a painting by Boileau. He built and endowed a school at Cheverell's Green, and a row of almshouses for sixteen paupers in the parish of Flamstead, Hertfordshire, where some of the family property lay. The Sebright bantam, which he created, is named after him and remains a popular breed of chicken to this day.
Works
In 1809 he published a letter to Sir Joseph Banks on The Art of Improving the Breeds of Domestic Animals. Sebright was also author of Observations on Hawking, describing the mode of breaking and managing several kinds of hawks used in falconry, 1826; and of Observations upon the Instinct of Animals, 1836. Charles Darwin commented on Sebright's practical skill as a breeder in The Variation of Animals and Plants under Domestication.
Family
He married, on 6 August 1793, Harriet, heiress of Richard Crofts of West Harling, Norfolk. She died in August 1826, having borne nine children:
Sir Thomas Gage Saunders Sebright, 8th Baronet. He married Lady Sarah Anne Hoffmann, daughter of Frederick Hoffman, Esq., Capt R.N.. Lady Sarah Anne is buried in the English Cemetery, Florence.
