Tech Mahindra, the new owner of India’s fraud-hit outsourcing group Satyam Computer Services, is enlisting the help of long-term partner BT as it seeks to rehabilitate the company.

The UK telecoms group holds a 31 per cent stake in Tech Mahindra, which took over Satyam in April. It is assisting with issues such as corporate governance and client relations, according to C.P. Gurnani, chief executive of what is now called Mahindra Satyam.
