New Delhi, Aug 08: Deputy Prime Minister L K Advani today rejected outright in Lok Sabha the Congress charge that BJP and the Centre were involved in "destabilising" its government in Arunachal Pradesh. "The Centre at no point of time tried to destabilise the government in Arunachal Pradesh or anywhere else," he told the House while replying to a short debate. Recalling that changes in government had taken place in Arunachal Pradesh, he described as "improper" the accusations that the Centre or the BJP had joined hands with underground outfits to destabilise the Congress regime in that state.
