Speculation over who is going to replace ousted Tata Sons chairperson Cyrus Mistry continues with British industrialist George Buckley and Tata International Managing Director Noel Tata’s names leading the list.

United Kingdom-based Sky News reported that Buckley was a major contender in the race to fill the vacant conglomerate’s top position. The Britain-based entrepreneur currently heads FTSE-100 engineer Smiths Group and unidentified officials told the news channel that initial negotiations are underway.

Reports about the group’s interim director Ratan Tata’s half-brother Noel being considered as a replacement also emerged. Other names being considered include Tata Consultancy Services Chief Executive Officer N Chandrasekaran and Tata Sons-owned Jaguar Land Rover chief Ralf Speth, The Economic Times reported.

Unidentified officials told the business daily that former Unilever Chief Operating Officer Harish Manwani is also being considered by the conglomerate’s board.

Mistry was ousted as chairperson on October 24. The Tata Group has accused Mistry of being responsible for its dwindling revenue. Mistry has dismissed the group’s allegations against him. In a letter to his employees, interim chairperson Ratan Tata had said the decision to sack Mistry was “absolutely necessary” for the group’s success.
