Asserting that the nation is "restless" for a change, Gujarat Chief Minister Narendra Modi on Thursday (August 15) launched a blistering attack on Prime Minister Manmohan Singh, challenging him for a public debate on pressing issues while accusing him of taking a 'weak' stance on Pakistan. Modi, BJP's poll campaign committee chief and virtually the party's face for the next Lok Sabha elections, lashed out at Singh in his Independence Day speech shortly after the Prime Minister had addressed the nation from the ramparts of Red Fort. In his extempore speech, an aggressive Modi criticised Singh on a range of issues including India's response to Pakistan and China, corruption, state of country's economy and food security bill. "Nation is restless for change," he said. "You are ruling a big country, we are managing a small state. I challenge the prime minister for a debate on the issue of development and good governance between government sitting in Delhi and our government," Modi said in his speech today during the state function on I-Day held at Lalan College ground in Bhuj.Modi compared the speech of President Pranab Mukherjee delivered on the eve of Independence Day with that delivered by the Prime Minister today and criticised the latter for not being tough in his speech on Pakistan. "The President has expressed his concern on the issue of killing of five of our soldiers. I had expected Prime Minister will raise the same concerns, but he has failed to talk tough," Modi said. Mukherjee had yesterday warned Pakistan that "patience has limits" and all "necessary steps" will be taken to ensure internal security and protect territorial integrity. Describing the Prime Minister's speech as a "big disappointment, Modi said it was lacklustre and failed to give any inspiration. "I am wondering that despite your name being included among those people who has unfurled the tricolour on the maximum occasions, you are saying the same things which were said by Pandit Nehru in his first address to our nation.In a debate moderated by TIMES NOW's Editor-in-Chief Arnab Goswami, panelists -- Chandan Mitra, Editor-in-Chief, The Pioneer and MP, Rajya Sabha, BJP; Rahul Narvekar, Spokesperson, Shiv Sena; Pavan Verma, Cultural Advisor to CM, Bihar; Manoj Jha, Spokesperson RJD; Sankarshan Thakur, Roving Editor, The Telegraph; Saba Naqvi, Political Editor, Outlook; Prasenjit Bose, Economist; Pavan Verma, Cultural Advisor to CM, Bihar and Capt Sushil Bhan, Columnist -- discuss whether, is it wrong to attack the Prime Minister on Independence day?
