Who is the man from Willingdon that assists Napoleon with business?

The man from Willingdon who assists Napoleon with business is Mr. Whymper. He plays a crucial role in the novel by acting as an intermediary between the farm and the outside human world. Mr. Whymper is a solicitor who helps Napoleon negotiate dealings and trade with neighboring farms, facilitating the animals' efforts to maintain and grow their new society. His presence underscores the theme of manipulation and the complex relationships between animals and humans in "Animal Farm."

In contrast, Mr. Jones is the previous owner of the farm, representing the oppressive human regime that the animals initially overthrow. Mr. Pilkington and Mr. Frederick are other farmers who represent different facets of human society and ultimately play roles in the novel’s climax, but they do not serve as Napoleon's business assistant like Mr. Whymper does.
