Congress party president Sonia Gandhi figures as the seventh most powerful woman of the world in the Forbes list which is topped by German Chancellor Angela Merkel and US Secretary of State Hillary Clinton.

Sonia Gandhi, 64, who is recouping from unspecified surgery in a US hospital, is ranked seventh just ahead of US First Lady Michelle Obama in a list of 100 most powerful women of the world released by the Forbes magazine.

Indian-American Indra Nooyi, the head of soft drink giant PepsiCo, has been ranked fourth, followed by Sheryl Sandberg, COO of Facebook and Melinda Gates co-chair and co-founder of the Bill & Melinda Gates Foundation.

Two Indian corporate executives Chandra Kochhar of the ICICI (43rd) and Kiran Mazumdar-Shaw of Biocon (99th) have figured in this list in which the third place is occupied by Dilma Rousseff, who became Brazil's first woman President.

"Lauded for overseeing heavy economic growth, she is also criticized for tolerating political corruption and failing to forge connections with India's fastest-growing demographic--younger voters," said Forbes about Sonia Gandhi.

"Gandhi is an avid scholar of the arts, and holds a degree in oil painting conservation. She recently underwent surgery in the US," it added.

"The managing director and CEO of India's second-largest bank, Chanda Kochhar rules over assets of USD 118 billion and profits of $ 1.35 million," Forbes said.

"India's first biotech entrepreneur, Kiran Mazumdar-Shaw founded Biocon in 1978 at just 25. Since then Biocon has become only the second Indian firm to list a $ 1 billion IPO on its first day of trading," it added.
