Edwardes’s father, Lord Kensington, looking forward in 1819 to the commencement of his eldest son’s political career, remarked that ‘whatever his views are I shall support them, but at present I think he is very much of my opinion’.
[Kensington] has been down to Canning at Gloucester Lodge ... to tender his son’s resignation of his seat ... the said son having voted with Burdett on Tuesday, although his seat was given him by Canning. The latter said he had observed Edwardes go out in the division, but behaved very handsomely indeed about it; said he was a young one and might think differently in the future, and, in short, desired that he might have his head and do as he liked for some time longer. But ... [Kensington] observed there was no chance of his mending, for ... his mother was in his confidence and he had entrusted to her his decided opinion against the government.Creevey Pprs. ii. 72.
Thereafter Edwardes confined his activities to the issue of Catholic relief, on which he was in agreement with his father: he voted for it, 1 Mar., 21 Apr., and paired for it, 10 May 1825. He relinquished his seat at the dissolution in 1826.
He had been admitted to St. John’s College, Cambridge as a fellow commoner in December 1825, though as at Oxford earlier, he did not take a degree. He died unmarried and v.p. at Brighton in August 1829, ‘of a rapid decline’. His address was then given as Llandawke, Carmarthenshire, and administration of his effects, valued at £200, was granted to his father.
