Although united on international trade issues and on questions of domestic reform, his cabinet also contained Lord Palmerston and Lord John Russell, who were certain to differ on questions of foreign policy. Charles Greville wrote in his "Memoirs", "In the present cabinet are five or six first-rate men of equal, or nearly equal, pretensions, none of them likely to acknowledge the superiority or defer to the opinions of any other, and every one of these five or six considering himself abler and more important than their premier"; and Sir James Graham wrote, "It is a powerful team, but it will require good driving", which Aberdeen was unable to provide. During the administration, much trouble was caused by the rivalry between Palmerston and Russell, and over the course of it Palmerston managed to out-manoeuvre Russell to emerge as the Whig heir apparent. The cabinet also included a single Radical, Sir William Molesworth, but much later, when justifying to the Queen his own new appointments, Gladstone told her: "For instance, even in Ld Aberdeen's Govt, in 52, Sir William Molesworth had been selected, at that time, a very advanced Radical, but who was perfectly harmless, & took little, or no part... He said these people generally became very moderate, when they were in office", which she admitted had been the case.
