Mildmay continued to sit for Winchester on the family interest controlled by his mother Lady Jane Mildmay. An active committee man and a ‘moderate’ Whig, increasingly at odds with both the city’s radicals and Tories, his main contribution in the reformed Commons was as a critic of the procedure for conducting election trials. His sympathy for those accused of bribery made him unpopular locally, but it was his unwavering support for the corn laws which ended his political career in 1841: a poignant reminder that not all Liberals backed free trade.
Mildmay’s father had sat for the ‘close borough’ of Winchester as a Pittite from 1802-7, on the Eastgate House interest he had purchased from Henry Penton MP.
A ‘moderate reformer’, who attended regularly, Mildmay was more active in the committee rooms than on the floor of the Commons.
At the unexpected dissolution at the end of that year Mildmay offered again for Winchester, where it was anticipated that he would secure the second votes of the Tories, being the more ‘moderate’ of the two Liberal contenders. His insistence on publicly voting for his more radical colleague, however, ‘lost him the election’ after the Tories withdrew support and solicited plumpers and his colleague, realising that only one of them could succeed, broke ranks and did the same.
In his final Parliament Mildmay continued to support the Whig ministry on most major issues, including Irish municipal reform, church and tithe reforms, and the poor law amendment bill, although he was among those who voted for allowing discretionary outdoor relief, 29 July 1838. He chalked up a string of votes against alteration of the corn laws, 15 Mar. 1838, 19 Feb. 1839, 15 Mar. 1839, 3 Apr. 1840, 26 May 1840, and remained firmly opposed to the ballot, much to the irritation of Winchester’s radicals.
On 9 Apr. 1838 Mildmay, a veteran of various election committees, had unsuccessfully urged the House to investigate further before considering penalties against John Sayer Poulter MP, who had accused the Shaftesbury election committee of incompetence and bias after it unseated him.
In his speech against convicting Webster, Mildmay had admitted that his unpopular stance on this matter ‘might be the last act of his political life’.
Mildmay, who had already maimed his left hand in a shooting mishap in 1824, died in May 1845 following an accident at his mother’s seat of Dogmersfield Park.
