Lascelles, who supposedly joined the navy at an early age before transferring to the army,
That spring he married into the Howard family, earls of Carlisle, whose politics and connections were largely Whig. Although Lord Harewood accepted the marriage, relations between him and the couple were strained at times, and the situation was no doubt exacerbated by the necessity of their living with him at Harewood and in London, as they could not afford to set up on their own. Lascelles had some heated exchanges, too, with his brother-in-law Lord Morpeth*, although his views became more tempered than those of his father and brother Henry. John Stuart Wortley* learned that ‘the old earl [his wife’s grandfather] is gracious and civil to him, which from what I had heard I hardly expected’.
In October 1826 Agar Ellis advised Lord Harewood to seek a government appointment for his son. Lascelles’s wife was keen on the idea, believing that it ‘might open a career for him’, but she had ‘no hope of any result, as all [Harewood’s] feelings are against it’. This hostility apparently stemmed not from any political disagreement, but from the earl’s distaste for political life and official men, which was such that ‘it would make him very uncomfortable to think of William in the midst of it’.
At the general election of 1831 Lascelles replaced his brother as Member for Northallerton. He divided against the second reading of the Grey ministry’s reintroduced reform bill, 6 July. He voted for use of the 1831 census to determine the disfranchisement schedules, 19 July, and against the partial disfranchisement of Chippenham, 27 July, and the bill’s passage, 21 Sept. He paired against the second reading of the revised bill, 17 Dec. 1831, and voted against going into committee on it, 20 Jan 1832. He agreed with Wrangham that Northallerton rather than York should be the polling place for the North Riding of Yorkshire, 24 Jan., and added that Beverley would prove most inconvenient for the East Riding. He divided against the enfranchisement of Tower Hamlets, 28 Feb., and the bill’s third reading, 22 Mar., and paired against the second reading of the Irish bill, 25 May. He voted against ministers on the Russian-Dutch loan, 26 Jan., 12 July 1832. The opening of Northallerton by the Reform Act meant that he was left without a seat at the general election later that year, though he may have been the Lascelles who was reportedly pressed by the Conservatives to contest Pontefract.
