I want to know the answer to the following question:
Who was the leader of the Rockingham Whigs?
All the background I'm provided with is that "As opposed to the instability of the earlier factions, which were often tied to a particular leader and could disintegrate if removed from power, the party was centred around a set of core principles and remained out of power as a united opposition to government.". Is that enough to answer the question?
Answer: no
