As private secretary to Lord John Russell and later Lord Palmerston, Grey was a steadfastly loyal Liberal member. A descendant of the Greys of Horton Castle, a merchant family of Newcastle who had acquired the Backworth Estate in Earsdon, five miles west of Tynemouth, in the early seventeenth century, Grey’s father, also Ralph William, the elder brother of Sir Charles Edward Grey, MP for Tynemouth, 1837-41, had succeeded to the family estates in 1812. After a long-running dispute over the right to work coal in Backworth, a copyhold township of the duke of Northumberland, the duke had purchased the Grey estates in 1822 for the sum of £160,000. Following the death of his father that year, an application was made to the court of chancery on behalf of Grey for a settlement of landed estate, and as a result, on coming of age, he succeeded to Chipchase Castle, on the north Tyne, in 1840.
At the 1847 general election, Grey was brought forward in the Liberal interest for Tynemouth. He declared at the nomination that he would ‘see that protection be fairly given to the shipping interest generally’, but being a supporter of free trade he refused to rule out reform of the navigation laws. His call for a custom house for the people of North Shields ‘in order to emancipate themselves from the tyranny of the more large and powerful town of Newcastle’ was a popular one, and he was returned unopposed.
Grey sought a return to parliament in March 1854, when he came forward for a vacancy at Liskeard. Facing two other Liberal candidates, the campaign was fractious and he was accused of being the dupe of the least progressive element of the government. His refusal to pledge support for the ballot caused further hostility, but he persevered and narrowly defeated his main opponent, John Trelawny.
Re-elected at Liskeard in 1857 after defeating Arthur Gordon, the son of Lord Aberdeen, Grey continued to back Palmerston, and voted for his conspiracy to murder bill, 19 Feb. 1858, and against the Derby ministry’s reform bill, 31 Mar. 1859. His devotion to the premier was attacked at the 1859 general election, with one newspaper stating that ‘Mr Grey is nobody when his master is out of office’ and ‘if he goes to the House again [he] will but do the bidding of Lord Palmerston, as he always has done’.
Despite Grey’s closeness to Russell and Palmerston, there is no evidence to suggest that he wielded any influence during his time as their private secretary, and he receives scant attention in biographies of the two Liberal leaders. In October 1869, while still a commissioner, he died, without issue, from an attack of internal haemorrhaging after an illness of only three days. A sympathetic obituary remembered him as ‘a man of very considerable powers, with singular quickness of perception, accuracy of judgement, and knowledge of character’.
