(Reuters) -India's Tata Consultancy Services is conducting an internal investigation to determine whether it was the gateway for a cyberattack on UK's Marks and Spencer that compromised customer data and disrupted the retailer’s operations, FT reported on Friday.

The Indian IT company, which has provided services to M&S for more than a decade, hopes to conclude the probe by the end of the month, the report said, citing people familiar with the matter.
