HYDERABAD, July 7: Sindh Adabi Sangat and Sindh Sughar Sangat Lok Adab Welfare Tanzeem demanded on Monday that all the languages of Pakistan should be declared national languages by making an amendment to the Constitution.

The leaders of the two organisations said after holding separate demonstrations outside the press club to mark the passage of Sindhi Language Bill on July 7, 1972 that the bill was one of the greatest feats of late Z.A. Bhutto.

They demanded that Sindhi language should be declared as exclusive national language of Sindh and one of the national languages of Pakistan.

Sindhi was an ancient language and it was the responsibility of present government to implement the bill in letter and spirit, they said.

They said that Sindhi was one of the richest languages of the world and deserved to be given the status of a national language. Only Sindhi should be used in official correspondence, they stressed.

A large number of writers and central office bearers as well as unit secretaries of Sindhi Adabi Sangat including Yousuf Sindhi, Parwano Bhatti, Zaib Nizamani Zahid Rajpar, Manzoor Ujjan and others staged a silent demonstration.
