‘Old Collett’, a wealthy hop merchant and ‘capable business man’, continued to be returned unopposed in absentia as a paying guest for Cashel, an Irish pocket borough placed at the disposal of the Liverpool ministry, to whom he gave steady and silent support.
Collett divided against Catholic claims, 6 Mar. 1827, 12 May 1828, and repeal of the Test Acts, 26 Feb. 1828. In early February 1829 Planta, the Wellington ministry’s patronage secretary, predicted that he would vote ‘with government’ for Catholic emancipation, but on 7 Feb. 1829 John Croker* recorded that he had ‘dined at the Speaker’s’, where ‘Peel made a joke about old Collett, who, not knowing Peel’s conversion, had written to him to say that he was hastening up to support the good old Protestant cause ... but in a moment he seemed to recollect himself, and looked very grave and almost discomposed at his own mirth’.
Collett died a widower in October 1833. By his will, dated 11 Oct. 1827 and proved under £300,000, he left Lockers House and lands on leasehold from St. John’s College, Cambridge, to his eldest daughter Mary (1797-1869), and provided £30,000 (with a further £10,000 in the event of marriage) to his eight surviving children, who included John (1798-1856), Liberal Member for Athlone, 1843-7, who shot himself dead in his library, and William (1810-82), Conservative Member for Lincoln, 1841-7.
