The decision comes on the heels of Nambiar senior turning 70.

The listed companies of the group include BPL Sanyo Utilities and Appliances Ltd, BPL Sanyo Technologies Ltd, BPL Refrigeration Ltd and BPL Engineering Ltd. TPG Nambiar had already announced his retirement from the flagship firm BPL Ltd at a board meeting held here on November 24.

Industry sources said Ajit G Nambiar would be heading these companies after a couple of board meetings. All the listed companies would take a final decision to this effect in their board meetings shortly. However, the Rs 3,500 crore group is not planning to hire anybody outside the family to head its major operations.

According to BPL officials, the company strategy does not allow anybody to be at the helm after attaining the age of 70. Regarding BPL, the chairman's post is a non-executive one and TPG Nambiar would continue to sit at the board meetings in the future. Ajit has been named chairman and managing director of the flagship company.
