The Tata-Corus saga

Last month, the UK Takeover Panel gave the two competitors time until January 30 to revise their bids.

It had said that in the eventuality of a competitive situation prevailing shortly before that date, it would decide the winner through an auction.

The Tata Steel's Board is scheduled to meet on January 30 to consider the earnings during the October-December quarter, but reports suggested that the meeting could be advanced to take into consideration the Corus agenda as well.
