Civil Aviation Minister Ajit Singh on Tuesday said it is important for India to allow Abu Dhabi-based Etihad Airways to buy stake in Jet Airways, a deal whose opponents, he said, are "long on politics and short on facts. The minister denied reports that he will quit the Prime Minister's coalition government if the deal collapses, and said it's for the Prime Minister's Office to confirm if the deal is on hold. That is not the case, clarified Dr Manmohan Singh's office.
