National Conference (NC) vice president Omar Abdullah on Wednesday lashed out at the Centre's move to invite foreign delegates to observe the ongoing assembly elections in Jammu and Kashmir, saying the polls were an internal matter of India. "I don't know why foreigners should be asked to check elections here. When foreign governments comment, then the government of India says 'this is an internal matter for India' and now suddenly they want foreign observers to come and look at our elections," Mr Abdullah said.
