Upbeat over reports of 60 Bharatiya Janata Party legislators demanding a change of leadership in Gujarat, the opposition Congress in the state assembly on Friday mounted a blistering attack on Chief Minister Narendra Modi and said 'his exit is certain'.

"The momentum that has gathered against Modi is not going to die down and his exit is certain," opposition leader Amarsinh Chaudhary said, while speaking on the budgetary demands of General Administration Department (GAD).

"Time takes its own course. The development that have taken place for last few days inside the House and outside are clear indication of what is in the offing," he said.

"Modi's condition at present is like Mahabharat's Arjun -- a great warrior, who had also to face defeat at the hands of a hunter despite all his skills," he said, while referring to last night's political developments during the birthday party of Rajya Sabha Member A K Patel demanding his removal.
