20 hours after Mamata Banerjee rebuffed Sonia Gandhi and the Prime Minister by suggesting he be made President of India, the Congress is returning fire. It said this afternoon that Ms Banerjee had acted irresponsibly, and that the Prime Minister isn't going anywhere. Senior Congress minister Ambika Soni said this afternoon that Ms Banerjee's behaviour "doesn't make political or ethical sense." She added, "Never has there been an instance where the name of a sitting PM is bandied about like this."
