ISLAMABAD (Agencies) - The main opposition party, Pakistan Muslim League Nawaz, said on Monday it would not support any unconstitutional action against President Asif Ali Zardari or his government but warned of protests if Zardari did not give up some powers. While some members of the PML-N, have called on Zardari and the two ministers to step down, the party has been circumspect. A spokesman for the PML-N said the party felt it was the moral duty of Zardari and the two ministers to step down, but it was up to them. If Mr Zardari and his ministers, who were covered by the NRO, do not resign, thats completely up to them, the spokesman, Siddiqul Farooq, told a news conference at the partys central secretariat. Farooq said the President being the symbol of the Federation as well as the supreme commander of the armed forces should not simultaneously hold the party office. PML-N would not be part of any unconstitutional move against Zardari, he said. Mr Nawaz Sharif has very clearly stated that democracy has to go on and if someone thinks that he will do something unconstitutional, he wont get our support, Farooq said. Farooq also said the party was not pushing early polls but said Zardaris party would pay the price when they are held. Farooq said his party could call for protests if Zardari failed to get rid of Musharrafs system. Farooq said his party wanted to see flourishing of democratic norms and rule of law in the country to attain peace, progress and prosperity. PML-N is ready to render more sacrifices for the cause of democracy, restoration of the original constitution and consolidation of rule of law.. He said PML-N does not believe in politics of confrontation and alleged that some leaders of Pakistan Peoples Party were issuing statements likely to vitiate the political atmosphere. Farooq urged the government to implement Supreme Courts verdict on NRO in letter and spirit and also called for repeal of the 17th amendment without any further delay. The PML-N leader said there should be true implementation of Charter of Democracy at the earliest to strengthen democracy in the country. He said no PML-N leader took benefit from NRO and justified the partys demand for resignations by NRO beneficiaries as cases closed under NRO had now been reopened under the top court verdict.
