Cotes continued to sit for Wigan on the Bridgeman interest with the concurrence of the Duke of Portland. At first he remained in opposition with the latter, voting against Pitt’s foreign policy on 12 Apr. 1791 and 1 Mar. 1792, and being listed a supporter of repeal of the Test Act in Scotland in 1791. In December 1792 his name was included in a list of Portland Whigs and in February 1793 he was considered a likely recruit to Windham’s ‘third party’. He certainly ceased voting with the minority and before the election of 1796 was listed ‘pro’ by the Treasury. No speech of his in the House survives, though there is evidence of the keen interest he took in promoting a controversial local road bill in 1796.
Cotes possessed considerable property in Shropshire and his substitution for his kinsman Sir Richard Hill
Although he was not listed a Treasury supporter after the election of 1812, Lord Liverpool’s half-brother assured him, 29 Oct. 1812, that Cotes ‘very seldom’ voted against government.
Cotes was described in 1810 as
the best old man in the world, adored in Staffordshire and Shropshire for his hearty good humour and welcome to everything that comes within a yard of him. He has a mania for farming, even to asking the people, rich and poor, whom he meets on the high road to come and look at his wheat, potatoes, etc.
Letters of Countess Granville, i. 13.
He died 24 Aug. 1821.
