Coming down heavily on the Uttar Pradesh government over the law and order issue, BJP president Amit Shah on Sunday said the ruling Samajwadi Party has failed on every front.Shah also attacked the Congress, saying the politics of obstructionism had become the hallmark of the opposition party at the Centre in the last two years and this is the reason it is weakening. "There is lack of development in Uttar Pradesh and there is no peace. Here, the atmosphere is of violence and the state government has failed to control all these," Shah said in his presidential address at the party's National Executive meet here.Raking up the issue of Kairana, in Shamli district, where Hindus are said to be migrating, and the Mathura violence, the BJP President expressed grief over the unfortunate incidents.He said: "The incident of Kairana where a large number of people are migrating is very unfortunate. The Mathura violence was also very unfortunate. The SP government here has been unable to control the situation."Shah said that the Bharatiya Janata Party's political rise is not due to the weakening of the Congress."The repeated obstructions in the path of development, which has become the hallmark of the Congress in the last two years, is the reason for its weakening," the BJP leader said, and added that the "rise of the BJP is not proportionate to the weakening of the Congress."He said: "The BJP is rising because of its ideology, the commitment of its workers and extraordinary commitment of the government and its leadership."
