I want to know the answer to the following question:
When did Burke leave the Whig party?
All the background I'm provided with is that "This provoked a reply from Fox, yet he was unable to give his speech for some time since he was overcome with tears and emotion, he appealed to Burke to remember their inalienable friendship, but also repeated his criticisms of Burke and uttered "unusually bitter sarcasms".". Is that enough to answer the question?
Answer: no
