Pierrepont, styled viscount Newark after the death of his elder brother, Charles, in 1850, represented the southern division of Nottinghamshire for over eight years, but is probably best known in the annals of the county’s political history for losing an 1851 by-election, even though he was backed by all but one of the region’s leading landowners. Newark was the second son of the 2nd Earl Manvers, one of Nottinghamshire’s wealthiest landowners. Manvers, an anti-Catholic Tory and former naval officer renowned for his ‘amiable, open sailor like habits’, represented Nottinghamshire from 1801 until his succession in 1816, which brought to an end the family’s 38-year occupation of one of the county’s seats.
As the heir to a major magnate, Newark’s early political ambitions were thwarted by sections of Nottinghamshire’s diverse farming community who were suspicious of the major landowners’ pretensions. In April 1849 he intimated that, providing there was no contest, he would offer for the vacancy at Nottinghamshire South, but according to the duke of Newcastle-under-Lyne, who was close to Manvers, the farmers, ‘would not hear of him’, and his candidature never materialised.
Newark was finally returned for Nottinghamshire South at the 1852 general election. At the nomination he declared that he no longer supported the Maynooth grant and ‘would now offer every possible resistance to the aggressions of the Romish priesthood’.
Maintaining his unwavering support for protection, Newark voted against Villiers’ motion praising the repeal of the corn laws, and abstained from Palmerston’s subsequent motion in favour of free trade, 26 Nov. 1852. On most other major issues he followed Disraeli into the division lobby and voted for his motion condemning the Crimean war, 25 May 1855, though, in opposition to the Conservative leader in the Commons, he divided against Roebuck’s censure of the cabinet, 19 July 1855. He also abstained from Cobden’s censure motion on Canton, 3 Mar. 1857. Explaining his position at the 1857 general election, he gave his staunch backing to Palmerston, arguing that he had ‘upheld on this occasion the interests and the honour of England’, but as a loyal Conservative, he had been ‘unwilling’ to oppose his party in the division lobby.
In another show of support for Palmerston, Newark backed the premier’s conspiracy to murder bill, 19 Feb. 1858. Thereafter he divided steadily with the Conservatives and voted for the Derby ministry’s reform bill, 31 Mar. 1859. At the 1859 general election he was noticeably equivocal over the merits of the bill, but criticised Lord John Russell for not allowing the measure to go as it stood into committee. He called for a moderate measure of reform that ‘recognized the tribute due to increased education and progressive intelligence’ and was returned without a contest for a third time.
Shortly after his succession, Newark rebuilt Thoresby Hall under the direction of the celebrated architect Anthony Salvin. He also took a keen interest in colliery and railway development on the expansive Thoresby estates, which included the village of Laxton, best-known for its preservation of open-field farming during the enclosure schemes of the nineteenth century. He was chairman of the Retford quarter sessions, 1884-93, and on the formation of the Nottinghamshire County Council in 1889, he was elected for the Edwinstowe division, which he represented until his retirement in 1898.
Newark died at the family seat of Thoresby Hall in January 1900, following a bout of influenza.
