Virgin Atlantic chief Richard Branson said he planned to invest about $50 million in his personal capacity in an Indian airline for which he was in talks with "four different people" in the country."Virgin Atlantic is not allowed to invest in India, but Richard Branson, I think, should be allowed to invest in India in his personal capacity," Branson said in an interview with NDTV Profit.Under the existing Indian aviation rules, no foreign airline is allowed to pick up stake in any domestic carrier.Maintaining that he was holding discussions with "four different people" in India who were in the aviation business, he said he planned to "invest $50 million in an Indian airline"."Some of them (four different people he was talking to) have got airlines up and running, and some are trying to set up an airline", he said when asked to name the people."I will be surprised if we don't reach an agreement in the next three to six months," Branson said, adding he was principally interested in a financial stake "but if some of them wanted my help and advice, I would give it willingly. But there are very capable people here."
