Women in the workplace was a central theme at the World Economic Forum's India Summit last month.  Following the release of the WEF's Global Gender Gap Report for 2009, the BBC's World Debate programme brought together some heavy hitters at the summit to discuss the promotion of gender parity as good business practice.  The participants: Carlos Ghosn, Chairman and Chief Executive Officer, Renault Nissan, France; Chanda Kochhar, Managing Director and Chief Executive Officer, ICICI Bank, India; Indra Nooyi, Chairman and Chief Executive Officer, PepsiCo; Melanne S. Verveer, US Ambassador-at-Large for Global Women's Issues; and Suhel Seth, business consultant and social commentator.
