Burger King, the global fast food chain, has announced plans to open 900 new sites in Brazil over the next five years, which would take its estate in the country past the 1,000 mark. The company has announced that it is to team up with private equity firm Vinci Partners to create a new company to expand its presence in the region, with the joint venture with Vinci becoming the brand master franchisee in Brazil for chain. Reports in Brazil suggest the company is set to invest up to $570m in its operations in the country, which it entered in 2004 and where it currently operates 108 franchise-owned restaurants. The US-listed fast-food group agreed a $4bn (£2.6bn) takeover from 3G Capital, a little-known US investment group, backed by Brazilian investors, in September last year.
