Jolliffe’s father grumbled about the ‘sacrifice’ of his son’s interest when he returned the 3rd Duke of Portland’s son-in-law for his borough of Petersfield on the first vacancy after Jolliffe came of age. His father returned him with himself at the ensuing general election, but he vacated soon after the meeting of Parliament to join his battalion in Ireland. He went on to serve in the Helder and Egyptian expeditions, returning home two months before his father’s death, when he became sole patron of Petersfield and returned himself. He first spoke in the House on a poor bill, 25 Nov. 1802. Portland may have secured him the offer of the governorship of Surinam, ceded by the Dutch, soon afterwards; if so, he did not accept it.
On the break up of Portland’s ministry, Jolliffe adhered to Canning. He voted with Perceval’s ministry on the address, 23 Jan. 1810, but was absent on the 26th: so Canning reported next day of ‘Jolliffe, who has not yet positively made his profession to me, but I know intends it’. He described him as his ‘tenth man’. Jolliffe joined Canning in opposition on 23 Feb. and 5 Mar. 1810, and on 30 Mar., although listed a government supporter in the consolidated list of the divisions, opposed ministers in the last division on the Scheldt inquiry. Canning had written a week before that he might let Jolliffe vote with opposition.
At the ensuing election he returned Canning with himself and, when Canning was elected at Liverpool, his cousin and namesake. He voted with Canning next session, supporting Catholic relief again (as also in 1817). When Canning came to terms with government in July 1814, he intended to solicit baronetcies for some of his friends, Jolliffe being first on the list.
Jolliffe, who had inherited his father’s claim to the Hylton peerage, did not press for it and in the end did not himself obtain the baronetcy offered him by Lord Liverpool in 1818, though a warrant for it was made out. He was said to have refused it, but his nephew accepted one in 1821. Famous as a sportsman and, in London, for the size and shape of his hat, he died 12/13 Jan. 1843.
