FRANKFURT: Tata Steel is likely to offer to sell parts of its European packaging activities to secure regulatory approval for a planned joint venture with Thyssenkrupp, three people familiar with the matter told Reuters. The two steelmakers on Wednesday agreed an eight-day extension to a deadline for submitting remedies to the European Commission, which has been concerned that the combined entity could hurt competition in some areas. The people said no final decisions have been made and remedy proposals could still change or be amended before the new April 1 deadline.
