Mansfield, a partner in the Leicester bank of Boultbee, Mansfield and Boultbee, came forward again as the corporation candidate for the borough at the general election of 1820. He withdrew briefly following an intrigue against him by the editor of the Leicester Journal, but in the event was returned unopposed.
He mustered for the divisions against more extensive tax reductions to relieve distress, 11, 21 Feb., but voted for admiralty economies, 1 Mar. 1822. When opposing the Newcastle petition on behalf of Henry Hunt*, which imputed ‘notorious corruption’ to the House, 22 Mar., he denied that ministerialists were ‘influenced by corrupt motives’:
He, for one, sat in that House, not by the influence of corruption, but by the unanimous choice of a large number of most respectable constituents; and though his vote had often been given in opposition to the opinions of gentlemen opposite, yet he had given that vote unbiassed by any undue influence or corrupt motive.
He presented petitions for relief on behalf of the woollen manufacturers of Leicester, 22 Apr., and from his constituents against the poor removal bill, 21 May. On 31 May 1822 he argued that the measure was ‘likely to prove as injurious to the poor ... as to those who were obliged to contribute to their support’; his wrecking amendment was carried by 82-66.
Mansfield, whose two elections for Leicester had cost him a total of £5,200, retired from Parliament at the dissolution in 1826, as he had planned to do for some time.
