Davenport, who was orphaned before he was six months old and was probably brought up by his uncle Sir Thomas Davenport, Northite Member for Newton 1780-6, was described by Lord Glenbervie in 1811 as ‘a pupil of J. J. Rousseau’.
His parliamentary conduct was markedly independent. The ‘Talents’ reckoned him ‘adverse’ to abolition of the slave trade, but he is not known to have opposed the bill in the House. After their fall he was reported to be wavering and likely to be swayed by the Foxite Lord Crewe
After the election of 1812 Davenport was described as a friend of the Liverpool ministry,
On questions of law and order, Davenport certainly rallied to government. He voted for the suspension of habeas corpus, 23 June 1817, in defence of the Scottish prosecutions, 10 Feb., and the use of spies, 5 Mar., and spoke and voted against Bennet’s motion on the imprisonment of persons for the sale of political tracts, 21 May 1818. He nevertheless voted against ministers on the Duke of Clarence’s marriage allowance, 15 Apr. 1818. Davenport sat on committees of inquiry into the cotton industry in 1809, 1811 and 1816, and on Peel’s cotton factories bill, 23 Feb. 1818, expressed his hostility to legislative interference, as he did on Moore’s bill to improve the lot of silk weavers, 13 May 1819. He welcomed the government’s concession of an inquiry into the salt duties, 10 Mar. 1818, but, disappointed by the outcome, he strongly condemned the tax, 18 Mar. and 29 Apr. 1819. He opposed the proposed equalization of the coal duties, 4 Mar. 1819. When Davenport voted for Calcraft’s motion to add Brougham to the Bank committee, 8 Feb. 1819, one observer named him among ‘government men’ who had gone against ministers on the issue.
