KARACHI: Pakistan Peoples Party (PPP) co-chairman Asif Ali Zardari on Thursday said that the the federal government has compromised on country's founding father Muhammad Ali Jinnah's principle of adherence to the Constitution by 'invading the province of Sindh'.

In a statement released by PPP's media cell, Zardari warned that the nation will slip into the quagmire of instability and uncertainty if the Constitution was trampled in this manner.

In his message of the eve of the 139th birth anniversary of the father of the nation, Quaid-i-Azam Mohammad Ali Jinnah, Zardari called upon the people of Pakistan to adhere to principles set by him in order to banish the militant and extremist mindset.

"Jinnah had envisioned a democratic and progressive Pakistan where there will be rule of law and every citizen will have equal opportunities to advance without any prejudice of religion, cast and creed. The need to follow this philosophy was never as great as it is now," said Zardari.

The former president maintained that every worker of the party will continue to fight for these values to make Pakistan a truly democratic state where constitution reigns supreme.

It is pertinent to note here that the federal government on December 22, rejected the summary sent to it by Sindh Chief Minister Qaim Ali Shah seeking to curtail powers of Rangers deployed in the province.

The interior ministry in a letter to the chief secretary of Sindh made it clear that the paramilitary force would continue to operate in the province with full powers.

PPP leadership reacted with dissent and anger to the decison, with Zardari's spokesman Farhatullah Babar also terming it an invasion of Sindh.

"The PPP will not permit this invasion of the provincial domain and warns against its consequences for the political stability of the federation," said the PPP senator.

Babar said that in the light of Article 147 of the Constitution, it is abundantly clear that the imposition of certain conditions on the authority of the Rangers as well as seeking ratification of those limitations from the Provincial Assembly is well within the constitutional rights of the provincial government.
