West, whose father was the placeman son of the courtier John, 2nd Earl De La Warr, was brought up at Chirk Castle and in London. His father, a Tory, had represented Denbigh Boroughs on his wife’s Myddelton interest in the 1802 Parliament and had hoped to make the seat his own, but he was defeated there in 1806 by his sister-in-law’s husband, the Foxite Whig Robert Myddelton Biddulph, who had also taken up residence at Chirk Castle.
West’s marriage in November 1820 was widely celebrated, and the lavish dinner with which he marked the coronation in 1821 encouraged speculation that he was about to be raised to the peerage.
The Wellington ministry counted West among their ‘friends’, and he divided with them on the civil list when they were brought down, 15 Nov. 1830. He was granted a fortnight’s leave ‘on account of the disturbed state of his neighbourhood’, 30 Nov. 1830, a time of unrest in the Wrexham area, Hampshire and Sussex. He voted against the Grey ministry’s reform bill at its second reading, 22 Mar., and for Gascoyne’s wrecking amendment, 19 Apr. 1831. At the ensuing general election East Grinstead, which was set to lose a Member under the bill, returned him unopposed, amid pro-reform demonstrations.
West’s interest in Denbigh Boroughs was enhanced through the addition of Wrexham to the constituency, but he declined requisitions to stand there or for Denbighshire at the 1832 general election. He remained out of Parliament until 1847, when he profited from local differences over the corn laws and church rates to come in unopposed for Denbigh Boroughs as a Liberal Conservative. He retained the seat, with one contest, until 1857, initially looking to Peel for patronage.
