Jolliffe’s membership of the reformed Commons is absent from most sources, which incorrectly identify his nephew Sir William Jolliffe as the MP for Petersfield after 1832 and the unsuccessful Conservative candidate at the 1835 general election.
Jolliffe’s petition against his opponent’s return, which centred around the eligibility of ‘cricket-field’ voters created by his estranged former agent Cornthwaite Hector, went in his favour and he took his seat, 6 Mar. 1833.
In his last parliament Jolliffe, who is not known to have spoken in debate, generally backed the Tory opposition, although he supported a radical motion for repeal of the house and window tax, 1 May 1833.
At the 1835 general election he offered again for Petersfield, but after a bitter struggle against Hector was ousted by a clear margin.
Jolliffe died in January 1843, leaving the Pall Mall residence where he had spent his declining years and the residue of his estate to Sir William. Stocks and shares were provided for his two illegitimate sons, Charles, aged 32, who inherited his Hylton estates in Cumberland and Durham, and George, aged 30, who received an annuity of £600.
