A scion of the network of aristocratic families which constituted the ‘Grand Whiggery’, Leveson was the most talented member of its younger generation, with an ‘exceedingly youthful, not to say boyish, appearance’.
Leveson’s father was an eminent diplomat, serving as ambassador to Russia, and to France 1824-8, 1830-4, 1835-41, and Leveson briefly served as an attaché at the British embassy in Paris, 1835-6.
I must write you a word to congratulate you on Leveson’s success last night. I never saw anything more promising in my life. He took all the strongest points, and showed great tact in the rapid and effective way in which he disposed. He cannot but be a good debater, if he perseveres.
Qu. in Fitzmaurice, Life of Granville, i. 27.
Another observer noted that Leveson’s voice ‘does not appear to be powerful, but it is clear and pleasant’, and his speech was attended by little gesticulation other than ‘a slight movement of his right arm’.
After being returned unopposed at the 1837 general election, Leveson was given the honour of moving the address to the Queen’s speech, 20 Nov. 1837, and gave a general endorsement of ministerial policy.
Leveson was obliged to vacate his seat in February 1840, after Frederick Howard’s return to England, and he became an under-secretary of state at the foreign office under Palmerston, 1840-1.
I like the thought of it very much. Though it is rather hard work, it is all of [a] pleasant kind ... I think I may be of use, from having more opportunities of seeing Lord Palmerston, and not being so dreadfully afraid of him. It is impossible to have a glimpse of him in the office. He comes down very late, having kept quantities of people waiting for him; and before he has seen them all goes down to the House. The clerks detest him, and ... [think] that he takes pleasure in bullying them.
Qu. in ibid., 29.
Leveson was prepared to stand as a second Whig candidate for South Staffordshire at the 1841 general election, but his services were not necessary as the parties shared the representation in a compromise.
On his father’s death in January 1846 Leveson succeeded to the peerage as 2nd earl Granville, and made his first speech in the upper house in favour of the repeal of the corn laws.
