Former Pakistan president Ayub Khan bought an Indian secret plan detailing its operations in Pakistan in 1965 from an Indian army Brigadier for only Rs 20,000. Disclosing this in an exclusive interview to The News, Gohar Ayub Khan, the former president’s son, said the Indian brigadier needed the money for his wife who wanted to buy equipment to fulfil her hobby of canning fruits and vegetables. He said Pakistani agents, active in New Delhi, exploited this passion of the brigadier’s wife and bought the plan. Gohar Ayub, now 68 years old, is writing his autobiography that will hit the market in December this year. He was witness to imposition of Pakistan’s first martial law by his father who ruled for 10 years. Gohar was Speaker of Pakistan’s National Assembly and Foreign Minister. Asked to name the brigadier, Gohar said he would give clear indications in his book to expose the identity of the Indian military officer, who is still alive. This would be a ‘‘bombshell’’ for the Indian army as the same officer later served at a very top position before retiring ‘‘honourably’’. He said he met the Indian officer in London in 1967. Gohar said Ayub Khan was preparing the Pakistan army to fight a war with India to ‘‘liberate’’ Kashmir. For this very purpose, he followed a long term policy.
