Former Pakistan Prime Minister Nawaz Sharif was deported to Saudi Arabia today, hours after his dramatic return to the country from a seven-year exile with the hope of posing a political challenge to President Pervez Musharraf.After over five hours of high drama, Sharif, who arrived here from London this morning to end his exile, has been deported to Jeddah once again where he spent six years from 2000, officials said.On his arrival, a team of Saudi and Pakistan officials held prolonged negotiations with him, asking him to honour an agreement he signed with the Saudi government to stay out of Pakistan for 10 years from 2000 following which he and his family were sent to Jeddah.Sharif, 57, was arrested on corruption charges after being kept at the aircraft for nearly 90 minutes, when only passengers were allowed to disembark. He was soon whisked away to an undisclosed location in a helicopter, and it was soon officially confirmed that he had been deported to Jeddah by a special plane.The combative former Prime Minister, who returned to Pakistan in a bid to topple the Musharraf regime, has ridden a political roller coaster since the beginning of his career in the 1980s.Born on December 25, 1949 in Lahore, Mian Muhammad Nawaz Sharif, the leader of Pakistan Muslim League-N (PML-N), was twice elected as Prime Minister of Pakistan but was not able to complete his term on both occasions.His first term was from November 1, 1990 to July 18, 1993. The then President Ghulam Ishaq Khan dissolved the National Assembly cutting short his rule. Khan was overruled by the Supreme Court, but Sharif chose to resign from office.The second term from February 17, 1997 to October 12, 1999 ended abruptly when he was overthrown by General Pervez Musharraf in a bloodless coup.His popularity had reached a peak when his government carried out a tit-fo-tat atomic tests on May 28, 1998 in response to India's nuclear tests two weeks earlier.Sharif, along with his then Indian counterpart Atal Bihari Vajpayee, undertook a major initiative in February 1999 to improve relations between the two countries, marked by Vajpayee's landmark Lahore bus visit.Sharif met Vajpayee at the Wagah border and a joint communique, known as the Lahore Declaration, was signed between the two leaders, which spelled out various steps to be taken by the two countries towards normalising relations.The Kargil fiasco of 1999 was a major embarrassment for his regime, though he claimed that Musharraf was the brain behind the Pakistani Army incursion into Jammu and Kashmir.
