Four days after Tata Sons chairman Cyrus Mistry was ousted by the board members, Tata group's chief of human resources NS Rajan had put in his papers on Friday, Indian daily Times of India reported.
Rajan, according to the report, was handpicked by Mistry. Speculations are rife that Rajan's exit has been triggered by Mistry's unceremonious ouster.
Rajan's removal has paved way for the two factions—Ratan Tata and Cyrus Mistry—to make allegations, and counter-allegations.
Mistry was removed due to "poor financial performance" and a "divergence" in values, media reports quoted company's trustee as saying.
In an explosive email to the board members of Tata Sons board, however, Mistry had leveled serious allegations against India's largest conglomerate for reducing him to the position of a "lame duck chairman". He also mentioned how he was removed without a "word of explanation".
