Veteran politician and one of the founding members of PPP, Dr Mubashir Hasan, passed away at his residence in Lahore on Saturday. He was 98.
Dr Hasan had been unwell and under treatment for the past three days. He is survived by his wife, Dr Zeenat Hussain.
It is said that the foundation stone of the PPP was laid in Dr Hasan's house in Gulberg, Lahore. A close aide of Zulfikar Ali Bhutto, he was also one of the contributors to PPP's first ever manifesto.
Along with J.A. Rahim and S. Mohammad Rashid, Hasan was one of the main architects behind organising the PPP across cities, towns and villages of (then) West Pakistan.
He was elected as a member of the National Assembly in 1970 and served as finance minister in Bhutto's cabinet from 1971-74.
He helped Bhutto in establishing the Ministry of Science in 1972 and was assigned the responsibility to arrange funding for Pakistan's nuclear project. He also helped establish the Kahuta Research Laboratories.
Later, Dr Hasan developed differences with the PPP and left to join Ghinwa Bhutto's PPP-Shaheed Bhutto. Three years ago, he also resigned from the Punjab presidency of Ghinwa's party.
Dr Hasan was also one of the founding members of the Human Rights Commission of Pakistan (HRCP) and the Pakistan-India People's Forum for Peace and Democracy.
Besides being a seasoned politician, he was a civil engineer, scientist, journalist and analyst and author of over 10 books.
The PPP's Punjab chapter expressed condolences on Dr Hasan's death. The chapter's president, Qamar Zaman Kaira, in a statement said Hasan "became the voice of the oppressed", adding that his services for the people would always be remembered.
The Human Rights Commission of Pakistan in a tweet also "deeply mourned" the veteran politician's death.
Awami National Party leader Afrasiab Khattak also said Hasan's death was a "huge loss".
Dr Hasan's funeral will be held at his residence in Lahore's Gulberg at 5pm on Saturday.
