Palmer’s family were long established in Bath and had played a prominent role in that city’s development in the eighteenth century. His grandfather, a prosperous brewer and tallow chandler, founded the Theatre Royal and his father, a driving force behind the development of the mail-coach system in the 1780s, served on the corporation and secured the parliamentary representation in 1801. He was ‘groomed for a gentleman’s life’, originally pursued an army career (serving in the Peninsula), and moved in the highest social circles, including the regent’s, ‘for which his agreeable manners ... amiable disposition and ... attainments, admirably qualified him’.
He was a fairly regular attender and continued to act with the Whig opposition to Lord Liverpool’s ministry on all major issues, including parliamentary reform, 31 May 1821, 25 Apr., 24 June 1822, 24 Apr., 2 June 1823, 26 Feb. 1824, 13, 27 Apr. 1826. He was absent from the division on Catholic relief, 28 Feb. 1821, but voted for it, 1 Mar., 21 Apr., 10 May 1825. He expressed no opinion on the charges laid against Queen Caroline, 26 June 1820, but condemned the ‘unmanly’ conduct of ministers in excluding her name from the liturgy, as ‘derogatory to the honour of the crown’ and ‘a most improper act on the part of men who complained of the revolutionary principles, infidelity and disaffection ... that were prevalent in the country’. On 9 July 1823, the last day of that session, he moved for production of the instructions sent to the ambassador in Madrid regarding the French military intervention in Spain. Asserting that the ‘crooked policy’ of ministers did not represent the views of the British people and that invasion was the policy of the Bourbon regime, not of the French people, he looked forward to Britain declaring war ‘for the liberties of France’ and joining hands with the French people to protect Spain’s independence. He said he had no wish to take the sense of the House and the motion was negatived without discussion.
Palmer offered again for Bath at the by-election in February 1829 occasioned by Brecknock’s appointment to office, but the outcome was a tie, and when another poll was held the following month he was defeated by two votes.
Palmer was returned at the head of the poll for the greatly enlarged Bath constituency in 1832 and sat as an advocate of ‘Whig principles’ until his defeat in 1837.
