"The prime minister has been in too much of a haste to invite Mr Nawaz Sharif. In fact, we should have waited to see what changes come about in Pakistan's attitude towards India and if there were some positive signs, surely he would have invited him," said BJP vice president Balbir Punj.
He also noted that Sharif was yet to take over as the prime minister. "It is too early and in fact it doesn't make much sense to invite him even before he had been sworn in," he said.
Congratulating Pakistan Muslim League-Nawaz chief Nawaz Sharif, Manmohan Singh on Sunday expressed India's desire to work with the new government in the neighbouring country and also invited Sharif to visit India.
