An army officer who had served in the Peninsula War, Greville, whose family were of ‘the high Tory party’, was first returned to Parliament after filling a vacancy at Warwick created by his elder brother’s succession as 3rd earl of Warwick in 1816.
Greville was, however, re-elected in first place at the 1835 general election, where he promised firm support for Peel’s new Conservative ministry, after colourfully describing the Whigs as a party who had ‘smothered themselves in their own dunghill’.
