Brian Steinberg Senior TV Editor Liquor giant Diageo PLC said it was severing ties with entrepreneur Sean Combs after the celebrity filed a suit alleging Diageo had not supported joint ventures involving Ciroc vodka and DeLeón tequila. Combs sued Diageo in late May in New York Supreme Court in Manhattan, alleging that the company, which also distributes Johnnie Walker and Captain Morgan, among other liquor brands, had neglected the spirits under their joint control. He also alleged Diageo had undermined the business by marketing Ciroc and DeLeón as “urban,” rather than something for the general market. In a filing made Tuesday in the same jurisdiction, Diageo called for the suit to be dismissed and said it would no longer be working with Combs, who over the years has launched a clothing line and restaurants and has a stake in the Revolt TV cable network.
