Japan's Sony Group Corp has sent a termination letter to Zee Entertainment Enterprises Ltd , citing its plans to call off the merger between its India unit and the media network, Bloomberg News reported on Monday.

Sony cited the unmet conditions of the merger agreement as the reason for the termination in a letter sent to Zee early on Monday, Bloomberg reported. The company is expected to disclose the letter to the exchange later, the report added.

Sony declined to comment, while Zee did not immediately respond to Reuters' request for comment.

The merger, which was announced more than two years ago, hit an impasse over the leadership of the merged company, amid a market regulator probe into Zee CEO Punit Goenka. (Reporting by Chandni Shah and Nishit Navin in Bengaluru; Editing by Sherry Jacob-Phillips)
