KARACHI - Awami National Party (ANP) Central Information Secretary Zahid Khan on Monday regretted over PML-N decision to quit present coalition and termed it harmful for the democracy. "The deficit of trust between top leadership of both PPP and PML-N caused PML-N to left the coalition government led by PPP," he added. He said that main stream political parties' leaders should think that Pakistan could not afford any political uncertainty and it would further increase the militancy in the country. "Its not 1988 that country could digest politics of conformation but volatile situation in the country and derailing the democratic government could prove suicidal not for the political parties but country's integrity would be put at stake," he said. "It is not a good omen for the democracy that a main stream political party left the coalition government. The country is facing worst insurgency in two provinces. I believed that without greater political harmony no party leader can alone fight with the menace of increasing religious extremism which is a great threat to integrity of the country," he added. Khan said that if any party leader wanted fresh elections by derailing the present coalition government then it would be disastrous for the integration of the country and pave way for religious insurgency to control all the provinces of the country. "It is need of hour that both Asif Ali Zardari and Mian Nawaz Sharif should rethink and take decisions with political maturity. It is impossible that election would be conducted in two provinces in NWFP and Balochistan while both provinces are facing insurgency."
