A young aristocrat and Conservative loyalist, Guernsey was a staunch though silent, supporter of the agricultural interest during his unremarkable parliamentary career. The namesake and heir of the 5th earl of Aylesford, who had represented Weobley 1807-12, Guernsey had blood ties with other noble (and Tory) Warwickshire families, being a nephew of Henry Richard Greville, 4th earl of Warwick and brother-in-law of William Walter Legge, 5th earl of Dartmouth.
Guernsey was returned unopposed as a Conservative for South Warwickshire at a by-election in June 1849, after promising to ’fight the battle of the English farmers’.
Guernsey succeeded as the 6th earl of Aylseford in 1859 and thereafter devoted himself to agricultural improvements and county pursuits, including prize-winning breeding of shorthorn cattle, before dying at a young age in 1871.
