PULIVENDULA, India (AFP) - Tens of thousands of tearful mourners paid their respects Friday as the popular chief minister of southern Andhra Pradesh state was buried in his private estate. YS Rajasekhara Reddy, 60, and four other men died Wednesday when their helicopter crashedas he flew to visit drought-hit villages. Protestant priests from the Church of South India offered a service at a church before Reddy was lowered into his grave in Pulivendula town. Screams of Long Live YSR, rang in the air and women openly wept at the funeral, to where Reddys charred body was ferried by an helicopter from Hyderabad. Politicians cutting across party lines flew to Hyderabad in droves to pay tribute to the father-of-two, who is credited with turning his native state into a modern hub for computer software, outsourcing and biotechnology. Reddy was elected five times to the Andhra Pradesh state legislature and three times to the national parliament. He will be remembered for his unwavering commitment to the development of Andhra Pradesh and his administrative acumen, Prime Minister Manmohan Singh said in Hyderabad. Several Indian states ordered official mourning while Andhra Pradesh lowered the national flag to half mast in a token of respect for the killed chief minister. The Times of India reported that the shock of his death had been too much for some, saying 10 people had died of cardiac arrest on hearing of his accident, while another four had committed suicide. Reddys son, Y.S. Jagan Mohan Reddy, tipped to take over from his father as chief minister, appealed to people not to resort to such extremes. Due to such acts (suicides) my fathers soul will not rest in peace... They should not resort to such acts, he told reporters. The Congress party, for which Reddy was an important regional powerbroker, is swiftly working out a succession plan to elect a new chief minister once a seven-day mourning period is finished. A majority of state leaders have passed a resolution to support Reddys son, but some leaders disagree and have said keeping the job in the family would be undemocratic.
