Tollemache, ‘a very tall and uncommonly handsome young man’, began his political career as a Tory before steadily moving over to the Liberals after 1846.
Tollemache’s early political career was entirely at the mercy of his father’s wishes, and at the 1831 and 1832 general elections Huntingtower opted to bring forward his youngest son, Algernon, for Grantham. Algernon represented the family interest in the borough until 1837, when he made way for Tollemache. Like his younger brother, whose party allegiance had been ambiguous, Tollemache informed the electors that he would represent them ‘unshackled and unpledged’, though he stated that his political opinions were ‘of a decidedly conservative character’.
Like his brothers, Tollemache is not known to have spoken in debate, and his select committee service was limited. A director of the New Zealand Company who owned a modest section of land in Wellington, he sat on the 1840 select committee on the colony,
Re-elected unopposed in 1841, when he was described as possessing ‘staunch Conservative principles’, Tollemache gave silent support to Peel’s ministry.
He gave the vote that had been objected to conscientiously, knowing that he should offend, and he felt assured that he had offended deeply. He rejoiced at the vote, and if the time were to come over again he should give the same. All the experiments in favour of free trade had proved favourable; and it seemed to him the less we shackled trade the more it progressed.
Tollemache also dismissed local criticism of his support for the Maynooth grant. Although he maintained that he was ‘no friend to the Roman Catholic system of religion’, he asked ‘did the electors think that the Church of England ... could be endangered by a paltry grant?’
Following his unopposed return in 1847, Tollemache’s votes in the Commons reflected his inexorable drift towards the Liberals. An occasional attender, he supported Lord John Russell’s Jewish disabilities bill, 17 Dec. 1847, the repeal of the navigation laws, 23 Apr. 1849, and Roebuck’s motion backing the government’s foreign policy, 28 June 1850, and opposed Conservative motions on agricultural distress, 21 Feb. 1850, 11 Apr. 1851.
At the 1852 general election, Tollemache’s proposer described him as ‘a fair representation of the Conservative liberal party’.
[H]e first came among them little more than a boy. He was then 22 years of age, and was he to live from that to 44 with his eyes shut? Consistency was not to go blundering on in error, but, if wrong, to get into the right way as soon as possible’.
Stamford Mercury, 9 July 1852.
However, the proselyte Tollemache, who was directly opposed by the second Conservative candidate, Lord Montagu Graham, cut an unpopular figure, and was defeated in third place, with one elector quipping that ‘Mr Tollemache had a right to change his opinions, and they had also a right to change their member’.
At the 1857 general election Tollemache offered again for Grantham. Now unambiguously Liberal, he lambasted the ‘do-nothing policy of the Conservatives’, backed Palmerston, and was returned in second place.
Tollemache restated his party allegiance at the 1865 general election, arguing that ‘Conservatism never mended anything until compelled; but Liberalism improved things as soon as they discovered a way of doing so’.
Tollemache died suddenly at Ham House, Surrey, in July 1888. He was survived by his daughter from his second marriage, Ada Maria Katherine, wife of Charles Douglas Richard Hanbury-Tracy, 4th baron Sudeley. The bulk of his estate, which was valued at £238,951 13s. 1d., was divided equally between his brother Algernon and baron Sudeley.
