Prime Minister Benazir Bhutto began a week-long visit to the US and Britain yesterday, but only after managing to postpone, at least for the time being, a major political crisis at home. During her visit to the United States she will address the United Nations General Assembly, and is also likely to hold talks with the top officials of the World Bank and the International Monetary Fund. Her meetings with the bank and IMF officials are especially crucial, as they may help her Government to retrieve Pakistan from a possible financial crunch next month. However, it was the political crisis at home which had been of real concern to Ms Bhutto. Her differences with President Farooq Ahmed Leghari, mainly on the distribution of power and key policy issues, had sharpened to the extent that in the past two days they had started to issue public statements against each other. Ms Bhutto indirectly accused the president and the main opposition leader, Nawaz Sharif of the Muslim League, of hatching a conspiracy against her Government. Mr Leghari reacted by criticising her for making 'unwarranted and irresponsible statements', and advising her to show 'grace and calm' while mourning the death of her brother, Murtaza Bhutto. A pre-arranged meeting between the leaders on Saturday, initially meant to discuss Ms Bhutto's foreign trip, turned into a six-hour session for thrashing out these differences. The talks did help in bridging the gap, but certainly did not resolve all the differences, as it was agreed that another round of talks will be held when Ms Bhutto returns from her foreign visit.
