ISLAMABAD - The Pakistan Muslim League-Nawaz’ ongoing protest in the budget session is fast becoming a source of agony for the treasury benches as several PPP MPs Thursday visited the Prime Minister Gilani and made complaints about the opposition party.During their separate meetings, Public Accounts Committee Chairman Nadeem Afzal Chan and MNA Jamshed Dasti condemned PML-N for its protest, saying: “The opposition should play their part in political stability and strengthening of democratic institutions.” They said the PML-N was undermining the supremacy of Parliament and appreciated the PPP leadership’s decision not to resort to tit-for-tat in the forthcoming budget session of Punjab. Similarly, PPP parliamentarians from Lahore called on Prime Minister Gilani at the Parliament House and rapped the PML-N over its protest in the Parliament.They said the opposition party should participate in the debate as they were elected by the people to represent them at the highest democratic forum. “They fell back on such tactics as they don’t have arguments,” said the visiting MPs.The parliamentarians included Samina Khalid Ghurki, Tariq Shabbir, Palwasha Khan, B Hasnain, Justice (r) Fakharun Nisa Khokhar Shakeela Khanum Rashid and Yasmeen Rehman.In an informal meeting, the other PPP lawmakers, including state ministers and advisers raised their concerns over the protest, saying that the opposition was enjoying an unprecedented freedom and therefore it should participate in the budget session in a constructive manner.
