Anil Ambani's wife, Tina Ambani, failed to appear for ED's questioning in the ₹40,000-crore fraud case involving Anil Dhirubhai Ambani Group (ADAG) and linked entities. Following this, the ED will issue a new summons, reported PTI. The Supreme Court directed the ED to constitute an SIT to undertake a "fair, independent, prompt and dispassionate" probe into the case last week.
