Henniker-Major, who was known by his Irish title Baron Henniker, was one of the ‘free trade converts’ who resigned their seat in 1846 after struggling with ‘both their consciences and constituents’.
At the 1832 general election Henniker accepted a requisition from 1,200 electors to stand in the Conservative interest for the newly-created division of Suffolk East.
At the 1835 general election Henniker stated that he had not been a factious opponent of the late Whig government, a claim given some credence by his vote for Lord Althorp’s motion to replace church rates with a land tax, 21 Apr. 1834. However, his opposition to a motion to allow dissenters to graduate at universities belied his insistence that he had ‘an honest sympathy for the conscientious dissenter, and would vote for the redress of his real grievances’.
Henniker backed Peel’s motion of no confidence in Melbourne’s ministry, 4 June 1841, and at the subsequent general election was uncompromising in his attack on the fallen administration, describing them as ‘vacillating, inconsistent, weak and unworthy’.
As Conservative Member for a predominantly rural county, Henniker had a strong relationship with Suffolk’s influential agricultural interest and he consistently voted to maintain the corn laws, 26 June 1844, 10 June 1845. However, following Peel’s introduction of the bill for their repeal, 27 Jan. 1846, Henniker too began to have a change of heart, and he was notable by his absence from a mass open air meeting of the East Suffolk Agricultural Protection Society held the same month. He sent a letter of apology, but unlike the other correspondence from those unable to attend, he did not give his support to the meeting.
Away from the Commons, Henniker, from his estates at Eye, remained a permanent fixture of county life, and in December 1856, with the corn law question long settled, he was the natural choice of candidate for the vacancy at Suffolk East, created by the death of the sitting Member Edward Gooch, who had himself replaced Henniker in 1846. Resurrecting his earlier image of a politician who would uphold the constitution while favouring ‘progress and reform’, he described himself as a ‘Liberal Conservative’ who would ‘go perfectly free and independent to the House of Commons’.
Though he described himself as a ‘Liberal Conservative’, Henniker followed Disraeli into the division lobby on all major issues, including for the Derby ministry’s reform bill, 31 Mar. 1859. Henniker condemned the bill’s defeat in his subsequent election address, laying the blame squarely on a ‘dexterous party manoeuvre’ by the Liberal opposition.
At the 1865 general election Henniker, who had seemingly given up any pretence of being free from party ties, launched a scathing attack on the Liberal government for its failure to address the reform question, though beyond praising the Derby ministry’s defeated 1859 reform bill, he declined to offer his own thoughts on the issue.
Hartismere died at his London residence in April 1870, following a sustained bout of bronchitis and congestion of the lungs.
Hartismere left effects valued at under £50,000 and was succeeded in the barony by his eldest son, John Major Henniker-Major, who on his elevation to the Lords had replaced him as Conservative Member for Suffolk East.
