Pakistan leader Nawaz Sharif is setting an example in his austerity campaign, urging countrymen to tighten their belts. The Prime Minister's Secretariat building in Islamabad is being sold and he has vacated his official residence, which is being converted into a state guesthouse. State guesthouses in Lahore, Karachi and Rawalpindi are also being sold to help pay foreign loans. The former President's House in Rawalpindi is to be converted into a university for women. Administrative expenditure in every government department has been cut by half. So has spending at the country's diplomatic missions abroad. In government offices and quasi-government organisations, spending has stopped completely. 'No new staff cars, furniture, refrigerators or air-conditioners will be bought,' Mr Sharif said. The austerity drive has extended to government salaries. Muslim League members have voluntarily reduced their salaries and allowances. Cabinet ministers are not being paid at all. Foreign tours by ministers are also out - apart from officials on important assignments. Even the practice of holding official functions in hotels is being halted. In a national address, Mr Sharif urged all Pakistanis to contribute to the austerity drive 'at this hour of national trial' by giving up expensive habits. 'The nation spends eight billion rupees every year on importing tea. For my sake, give up half the tea that you consume in your home or office or shop,' he said. 'Take it as if you have offered me these cups of tea. If you forego half the tea that you drink, we shall save ourselves four billion rupees.' He asked them to make similar savings on imported cooking oil - imploring every Pakistani to save at least one spoonful a day 'in the name of the nation'.
