Howorth came of an old Herefordshire family, a cadet branch of which had settled in Radnorshire. He was great-nephew of Sir Humphrey Howorth, Member for Radnorshire 1722-54,
a constant frequenter of the different billiard tables and tennis courts, to whom I had lost many sixpences. I had never heard his name, and considered him to be one of the numerous herd of pettifogging little sharpers who were constantly upon the look out in the hope of fleecing some novice or unwary young man, nor do I believe I was much mistaken in forming such an opinion of Mr Howorth at the time I so used to meet him.
When Howorth was about to return to England some years later, Hickey reported that he had acquired ‘a large and rapid fortune of at least £40,000, from getting a slice in the opium contract’, which he determined to enjoy in England. He went on to purchase Hickey’s father’s house in London and became ‘a regular frequenter of Newmarket, and kept racers’.
Howorth had joined the Whig Club 6 Feb. 1787 and was a Friend of the People. In 1796 he was rebuffed in a bid to get into Parliament for Evesham and again failed there in the contest of 1802. Fox sent him down to Bridgwater in 1804 to contest a by-election, but he backed out.
Howorth henceforward acted with the Whig opposition, though not the steadiest of attenders. His chief interest in debate was Indian affairs, on which he had first spoken on 20 Apr. 1807. On 15 Mar. he voted and on 31 Mar. 1808 spoke against the Marquess Wellesley’s conduct towards the nawab of Oudh, calling himself a friend of (Sir) Philip Francis. He took the same line on the Carnatic question, 17 June. He had opposed financial relief for the East India Company until its budget was presented, 26 Apr. 1808, but he was not an opponent of their commercial monopoly, 9 June 1809. He deplored ‘the lingering existence of an expiring charter’, 15 June 1812, pressing as a select committeeman for more information on the Company’s financial plight. He opposed the renewed charter, June-July 1813, complaining of the concessions to the ‘commercial clamours of the out-ports’ without reference to the welfare of the people of India. He voted against Christian missions to India at that time. He opposed the Company pension awarded to Lord Melville, 24 May 1815. On 15 May 1818 his motion for information on the war in India was in part agreed to; he did not oppose the vote of thanks to Lord Hastings on its conclusion, 4 Mar. 1819, but again called for more awareness of the consequences of acquiring fresh territories in India. He was also active in debates at India House and a chairman of the committee of bye-laws there.
Howorth had little to say on other subjects. On 13 June 1809 and 17 May 1811 he attempted to prevent the exemption of foreign investors from taxation, threatening to renew his campaign ‘year after year’, but he did not do so. Thomas Creevey, labelling him a ‘Newmarket financier’, deprecated his pretensions to any prominence in Whig councils, though he was listed one of their adherents in March 1810. Perceval was prepared to see him on the finance committee in 1810, though he voted for Madocks’s motion against ministerial corruption, 11 May 1809. He supported Catholic relief throughout, when present. On 21 May 1812 he voted for a more efficient administration. He supported sinecure reform, 4 May 1812, 29 Mar., and the claims of John Palmer to compensation, 31 May 1813. He opposed the alteration in the Corn Laws, against which he presented petitions on 6 June 1814 and 10 Mar. 1815. He voted against the renewal of war, 28 Apr. and 25 May 1815, and in that and the following session voted steadily for retrenchment. On 14 Mar. 1816 he presented a petition, with which he concurred, against the property tax. In April 1818 he was one of the sporting Whigs who would not leave Newmarket to vote against the ducal marriage grants.
Howorth retired in 1820, handicapped by an asthmatic complaint. He died at his country retreat at Banstead, 14 Sept. 1827.
