Remembered by the Whig diarist Creevey as ‘an agreeable playfellow’, Grosvenor was heir to the vast estates of the marquesses of Westminster, then as now one of Britain’s wealthiest families.
At the 1832 general election Grosvenor opted to stand for the newly-created division of Cheshire South, where Eaton, which so impressed the young princess Victoria during a visit there in October 1832, was located.
In his final stint in the Commons, Grosvenor continued to give the Whigs general support in the lobbies, through he remained opposed to Jewish emancipation, against which he voted on at least one occasion, 22 May 1833. He served on the Linlithgow election committee, 30 Apr., and brought up its report confirming the result, 6 May 1833. He is only known to have spoken three times. In a speech that was ‘inaudible in the gallery’ to most of the reporters, 10 Mar. 1834, he defended the renumeration of the yeomanry corps, saying that they could not be expected to ‘defray all expenses from their own pockets’, and raised the issue of whether it was ‘constitutional to allow bodies to arm themselves’ without pay.
In June 1834 dissatisfaction with Grosvenor and his colleague was reported in the local press, after they declined to contribute to the Chester races.
Grosvenor is chiefly remembered today for his acts of munificence and exceptionally shrewd custodianship of his family’s London property portfolio, to which he continually added, especially after his succession as 2nd marquess of Westminster in 1845.
As marquess of Westminster, he rarely spoke in the Lords but remained active on behalf of his former constituents, for instance backing the campaign of Cheshire’s salt producers against the salt monopoly of the East India Company in the 1850s.
A martyr to gout, Grosvenor died at Fonthill in October 1869 from a malignant carbuncle.
