Bharti Airtel Limited (BSE:532454) is in talks to sell 40% stake in Bharti Infratel Limited (NSEI:INFRATEL). Bharti Airtel is already in talks with KKR & Co. L.P. (NYSE:KKR).

A committee was studying whether the sale would be a minority stake or control of the tower unit and a decision could be taken in a month, Mittal said. Bharti Airtel is also considering mergers or stake sales at some of its Africa operations as it looks to cut debt and make its biggest overseas acquisition profitable. The moves would pare the size of operations in the continent and could be completed within a year, Chairman, Sunil Bharti Mittal said in an interview with Bloomberg Quint at the World Economic Forum in Davos.

Some of Bharti's businesses in 15 African nations would be affected, he said.
