‘An efficient member of the House and an authority on naval questions’, Hay came from a well-connected Scottish landed family.
Hay initially canvassed at Wakefield in June 1860, when he noted that he could already have been in Parliament had he offered as a Liberal. However, although a Conservative, he was ‘not so rabid... as to wish to overthrow a Ministry which might be doing good service’, particularly as he considered Palmerston ‘a tolerably sound Conservative at heart’. A member of the Scottish Kirk, he voiced sympathy with the Church of England, and was keen to see the church rates issue resolved by a measure which would ‘relieve conscientious Dissenters’, such as that advocated by his brother-in-law, John Hubbard (MP for Buckingham).
Hay informed his constituents in 1862 that ‘he was not a talking member, but he attended on the Committees’.
Disregarding Palmerston’s requests to drop the matter, Hay pressed another issue of concern to naval officers, the lengthy delays in distributing prize money, notably in relation to the capture of Kerch (1855), at which Hay had served, 8 July 1862.
Hay generally divided with the Conservative party, opposing the ballot and franchise extension, and the abolition of church rates and university tests. Although preoccupied with naval matters, he did pursue other issues. Together with three Scottish MPs, he introduced the bank notes (Scotland) bill, 16 Mar. 1864, which aimed to increase the supply of paper money by allowing any Scottish bank to issue notes against gold, but did not press it to a second reading, 27 Apr. 1864.
While there was much truth in the Leeds Mercury’s assertion that Hay ‘would be a representative of the navy and not of Wakefield’, he did not wholly neglect local concerns.
Hay was defeated by a local Liberal opponent at Wakefield in 1865. At the hustings he was rather more critical of Palmerston’s foreign policy than in 1862, and had to defend himself against charges of having spoken disrespectfully of the premier.
Hay resumed his questioning of the government on naval matters. When Derby took office he was appointed as a lord of the admiralty in July 1866, whereupon he resigned all his directorships except Reuters and the Portpatrick railway, and was re-elected unopposed at Stamford.
Although no longer in office, Hay maintained his keen interest in naval matters after he was re-elected unopposed for Stamford in 1868, protesting on his own behalf in 1870 when he was compulsorily placed on the retired list.
