The Press Trust of India quoted him as saying: "Once the shareholders approve the proposal, Corus will be delisted from stock exchanges and would function as a subsidiary of Tata Steel from April."
The takeover will make Tata Steel, the flagship of the Tata empire, the world's fifth-largest steelmaker, vaulting from 56th place after it beat Brazilian rival CSN in a bidding contest for Corus in January.
At a function marking the 168th birthday of the company's late founder, Tata said: "An integration committee will be set up to oversee the merger of Tata Steel and Corus."
Tata said after a meeting with James Leng, Corus's chairman, that the committee would comprise representatives from both companies.
Leng is likely to be deputy chairman and serve as a director on the Tata Steel board, a company official who wished not to be named told AFP by telephone from Jamshedpur, where Tata's largest steel plant is located.
