Chandigarh, Oct. 22 :    Chandigarh, Oct. 22:  After lying low for almost two decades, separatist outfit Dal Khalsa is trying to reinvent itself as a mainstream political party. The organisation plans to make a comeback with the next Shiromani Gurdwara Prabandhak Committee elections. But first it has to ensure the return of chief Gajinder Singh from Pakistan. Gajinder, who led the hijack of an Indian Airlines plane to Pakistan in September 1981, has served a 14-year jail term in prisons across the neighbouring country. The plane, on its way from New Delhi to Srinagar, was hijacked to protest the arrest of Jarnail Singh Bhindranwale in the Lala Jagat Narain assassination case. Dal Khalsa vice-president Satnam Singh, a co-accused in the hijacking, had shocked Indian intelligence agencies by reaching Punjab through the Nepal border last year. Satnam presented himself at the Delhi High Court, which acquitted him as no case was pending against him. Sources said Gajinder might sneak into India in a similar manner. 'We have been insisting that Gajinder Singh return to his homeland to lead the organisation,' said Kanwer Pal Singh, a Dal Khalsa leader. He added that there was no case pending against Gajinder in Punjab. 'It is important for him to return to fill the gap in the Akali leadership as most of them have been discredited,' he said. The Dal Khalsa, banned by the Punjab government in May 1982 for raising the demand for Khalistan, has announced that it will participate in the coming SGPC elections. The ban on the outfit was lifted in May 1992. 'It would be proper to first concentrate in reforming the shortcomings that have plagued the SGPC,' a brochure brought out by the outfit says. The Dal Khalsa had contested the SGPC polls against the Akali Dal in 1979 but had failed to win a seat.
