Edwards, whose brief tenure as Member for Glamorgan was ended in 1820 by the concerted opposition of the local gentry, left behind a reputation as an opportunist, an unscrupulous demagogue and ‘a low lived blackguard’, whose canvassing methods consisted of ‘a large distribution of ale and money’.
Prior to 1825 fears had persisted in Glamorgan landed circles that he planned to make another attempt on the county at the next general election.
The Wellington ministry regarded him as one of their ‘friends’, but continued ill health prevented him from taking much part in parliamentary proceedings. He was absent from the crucial civil list division, 15 Nov. 1830. He attended to vote against the second reading of the Grey ministry’s reform bill, 22 Mar., and paired for Gascoyne’s wrecking amendment, 19 Apr. 1831. Defying expectations, he offered for Wells at the ensuing general election and defended his opposition to a measure that would have deprived the freemen of their privileges and increased the representation of ‘Catholic Ireland’. However his later statement, expressing the hope that the next bill would be framed in such a way as he could support, helped to avert a potentially dangerous contest and allowed him and Lee to come in unopposed.
Edwards Vaughan died in August 1833 and left all his real estate to his son by his second marriage, Nash Vaughan Edwards Vaughan (1811-68), who later inherited Nash’s property. His wife and son were named as guardians of ‘the property and estate of my son (by my first wife) John Williams Edwards’, who was still living. His personalty was sworn under £14,000.
