Problems at Kingfisher continues to weigh down on Vijay Mallya with his net worth dipping by USD 50 million in the past one year to USD 750 million, pulling down his position in India's 100 richest list by 11 places to 84th.

In Forbes latest list of 100 richest released today, Mallya is ranked at 84th position in 2013, a drop from 73rd place in the preceding year.

Last year, Mallya had a fortune of USD 800 million. Earlier in March this year, Mallya was dropped from Forbes global rich list, while he had moved out of the billionaire league last year itself.

Burdened with huge losses and large debts, Kingfisher Airlines stopped flying in October 2012 and its flying licence also lapsed about two months later.

A stake sale in his group firm United Spirits to Diageo and rising shares of United Breweries, a beer venture with Heineken "have kept this one-time billionaire afloat," Forbes said in its latest list.
