TCS, which has worked with M&S for over ten years, aims to finish the probe by the end of the month. In 2018, the retailer moved half of its tech work to TCS, designating it as its main tech partner. In 2023, they expanded their partnership to update all of M&S's tech systems. During the attack, at least two TCS employees' M&S login details were used in the breach. At M&S Reliance, a 51:49 joint venture between M&S and Reliance Retail, sales rose by 5% in FY24, reaching Rs 1,742 crore.
