Keck’s grandfather, a successful barrister, married the heiress to the Beaumont estates and sired an ‘opulent and respectable’ county family.
Keck surfaced in opposition to the Grenville ministry. He was in the minorities on India and against the repeal of Pitt’s Additional Force Act, 21 and 30 Apr. 1806, and on 6 May spoke against the repeal, pointing out that his county had met its quota. He was listed ‘adverse’ to the abolition of the slave trade. On 21 and 22 Apr. 1807 he spoke, as a member of the Penryn election committee, in favour of proceedings against (Sir) Christopher Hawkins. He spoke on the militia bill, 18 May 1808. Regarded as a supporter of the Portland administration,
Keck was on the Treasury list of supporters after his re-election in 1812. On 7 Dec. he presented the county clergy’s petition against Catholic relief, which he opposed throughout that session and again in 1817. He voted for the abolition of one of the paymasterships-general, 8 Mar., and for the sinecure regulation bill, 29 Mar. 1813. On 16 June 1814 he objected to the imperfections of Samuel Egerton Brydges’s poor settlement bill, but let it proceed when some clauses were withdrawn. He was in the minority on the civil list, 8 May 1815, but in the majority on the Regent’s expenditure, 31 May. He opposed the army estimates and the property tax, 6-18 Mar. 1816, but vindicated the conduct of the mayor of Leicester in declining an unsatisfactory requisition for a town meeting against the tax, 11 Mar., and rebuked opposition for seeking to make political capital out of it. On 24 Apr. 1816 he took a month’s sick leave.
Keck’s concern about the activities of the Hampden clubs, whose members he dubbed ‘Luddites’, was indicated in his letters to the Home secretary in the autumn of 1816: unless government checked them, he wrote, ‘we shall probably have to contend with them in arms at their own chosen time’. In December he was reported as saying that ‘he was totally against the present measures’. In January 1817 he and two magistrates were forced out of Oadby, where they had gone to swear in special constables, whereupon he summoned the hussars from Leicester with a troop of his yeomanry to restore order.
At the election of 1818 Keck was discouraged by reports of his unpopularity due to ‘the part he took in favour of Oliver, and the determined and spirited manner in which he met the late disturbances of the manufacturing districts’, and declined a poll—he had never faced one. Regarding it ‘more as my own cause than that of the public, and in an indifferent state of health produced by great anxiety’, he benefited from a backlash against the manoeuvre whereby he was replaced by Charles March Phillipps. So ‘no sooner was the election over, than he began to canvass ... and keep open house with a view to the next general election’.
