A famous bibliophile, Miller cut a poor figure on the platform, where he was ‘notoriously tongue-tied’, and he offered only silent support for Conservative principles during his time in the Commons.
Miller was returned in first place at the 1832 general election and in the following session supported Matthias Attwood’s motion for currency reform, 24 Apr. 1833, and the proposals of Sir William Ingilby and Sir John Key to reduce malt duty and repeal house and window tax respectively, 26, 30 Apr. 1833. He opposed the appropriation of surplus Irish church revenues. Prior to the 1835 general election, Miller unsuccessfully beseeched the premier Sir Robert Peel to persuade his brother, Edmund, to withdraw from the Newcastle-under-Lyme contest.
Miller is very unpopular in the town & if any third candidate offers, he must expend a very large sum to secure two seats. He could not poll more than 100 votes without having recourse to bribery. £1500 of his last election expenses remains unpaid.

During the campaign Miller said that although he had not been a supporter of the Grey ministry, he had never given them a ‘factious or vexatious opposition’. At times he had even backed the government and he had ‘absented [himself] from that House … when he could not honestly oppose the[ir] measures, and when to have given them his support would have been only to swell the ministerial majorities’ and so delay the return of the Conservatives to office.
Thereafter Miller opposed political reforms, such as the ballot and equalisation of the borough and county franchises, and resisted free trade, but he backed the call for the immediate abolition of slave apprenticeships in 1838. He supported the votes of no confidence in the Melbourne administration, 31 Jan. 1840, 4 June 1841, and offered a stout defence of the corn laws at the 1841 general election.
On his death in 1848, Miller, a bachelor, left property worth £300,000 as well as his impressive library of rare books to his cousins, the Misses Marsh, from whom it passed in 1862 to another cousin Samuel Christy (1810-89), also a Conservative MP for Newcastle-under-Lyme, 1847-1859.
