ISLAMABAD - Former FBR chairman, Abdullah Yusuf, Saturday asked the government to raise oil prices otherwise worsening circular debt issue would prove like a 'bombshell' that might lead to a collapse of complete electricity and oil supply chain across the country. He said that decision to keep oil prices unchanged despite rising trend in the global market would result in worsening circular debt issue. He was addressing the third Oil and Gas Pakistan 2011 Forum here on Saturday. Abdullah Yusuf said that oil-pricing issue had been politicised, as the government withdrew the decision of hike in oil prices on January 7 after facing a pressure mounted by other political parties. "Government made a wrong decision in 2007 not to pass on the rising impact of oil prices to the consumer that resulted in Rs 175 billion circular debt".
