P Chidambaram, former Finance Minister and a top leader of the opposition Congress party, has been accused formally of corruption by the CBI today and will stand trial in what is known as the Aircel-Maxis case once the chargesheet is cleared by the judge. The CBI named Mr Chidambaram, 72, in a chargesheet filed in a Delhi court today, hours ahead of a no-trust vote against Prime Minister Narendra Modi which he is placed to win easily. The Congress is among the opposition parties backing the no-trust vote.
