Hawkins, who had inherited ‘extensive estates and several profitable mines’ from his father at the age of 12, became the ‘great Cornish borough Leviathan’, returning at various times one or both Members for Grampound, Helston, Mitchell, Penryn, St. Ives and Tregony. However, he never obtained the peerage that he coveted, presumably because of the prosecution in 1807-8 for bribery and corruption at Penryn, which almost led to his expulsion from the Commons. By 1820 his electoral influence had ‘greatly diminished’, and though he returned one Member for Mitchell at the general election that year, his candidates for Helston and St. Ives were defeated and he lost his own seat at Penryn. His bitter rival Francis Basset, 1st Baron De Dunstanville, observed: ‘Poor Sir Christopher beaten everywhere, and to render his mortification complete, everyone laughs at it’. In fact, he partially rebuilt his interest at Penryn, and in May 1821 he was returned unopposed at a by-election for St. Ives, where he was lord of the manor.
He was an occasional attender who gave continued support to Lord Liverpool’s ministry. He voted against Hume’s economy and retrenchment motion, 27 June 1821, and more extensive tax reductions, 11, 21 Feb. 1822. He divided against repeal of the Foreign Enlistment Act, 16 Apr., and inquiry into the prosecution of the Dublin Orange rioters, 22 Apr. 1823. He presented a St. Ives petition for repeal of the coastwise coal duty, 16 Feb. 1824.
Hawkins divided for Catholic relief, 6 Mar., and was granted one month’s leave, ‘having sworn off’, 6 Apr. 1827. He addressed the House on the Penryn election bill, 18 May, but was ‘totally inaudible in the gallery’. He presented a Cornish petition for repeal of the Test Acts, 7 June 1827.
