Wrigley shareholders on Thursday gave the green light for a 23-billion-dollar takeover of the US chewing gum manufacturer by candy giant Mars, reported dpa.
Mars announced the deal in April that propels it to world's largest candy maker with revenues of 27 billion dollars.
Billionaire US investor Warren Buffett was also part of the takeover and will control a minority share of the firm's stock.
The family-controlled Mars firm is known best for its Mars and Snickers bars.
