"BT has a 24.4 per cent shareholding in Tech Mahindra. Tech Mahindra remains a key supplier to BT and, while further sales may be considered in the future, BT expects to continue to have a shareholding in Tech Mahindra for some time," a BT spokesperson said.
There were speculations that BT may exit in view of likely merger of Mahindra Satyam and Tech Mahindra.
In November last year, BT had sold 5.5 per cent stake in Tech Mahindra to the IT company's parent firm Mahindra & Mahindra.
Tech Mahindra was developed from a joint venture between the two companies in 1986.
M&M held 48.17 per cent stake in Tech Mahindra, while BT held 23.46 per cent and Mahindra BT Investment Company Mauritius Ltd held 0.05 per cent stake as of March 31, 2011, according to data available on the Bombay Stock Exchange website.
BT, which has a significant presence in India, is also ramping up in the country.
It has also set up a New Delhi Technology showcase centre, which was inaugurated on Tuesday.
