Tata Motors said Carl-Peter Forster "has ceased to be the group CEO and MD, with immediate effect, due to his unavoidable personal circumstances".

Forster will, however, remain a non-executive board member. Prakash Telang, MD of India operations, and Ralf Speth, CEO of Jaguar Land Rover, will represent their respective operations on the board.

Ratan Tata, chairman of Tata Motors, said: “The board respects Carl-Peter’s personal circumstances that led to this move. We would like to thank him for his contributions to the successful development of our company in his role as group CEO and MD. We are looking forward to continue to working with him as a non-executive member of the board.”

Forster said: “I deeply regret that my personal circumstances make it difficult for me to continue to perform the challenging duties of managing the thriving global activities of the Tata Motors Group with its main activities in India and the UK and increasingly in additional overseas markets. I am glad to continue my association with Tata Motors.”
