“Yes, we are in negotiation with Diageo to acquire RCB for `250 crore to `300 crore,” JSW Group sources said on Wednesday.The RCB franchise, which is now eight IPl seasons old, is a wholly owned subsidiary of United Spirits limited (USl), in which Diageo has a majority stake. Talks have been going on for a long time but the deal couldn’t come through because of the public spat between Diageo and former promoter Vijay Mallya over alleged diversion to Kingfisher and their UB Group entities.
