Given the grit of Prime Minister Narendra Modi, Kashmir problem will be solved by 2019, senior BJP leader Subramanian Swamy claimed on Monday, even as he pitched for undertaking major economic reforms once the NDA Government "puts house in order" to become leading economy of the world. "Sardar Patel, the man who welded 600 kingdoms into one India...Sardar Patel sat with each of them... and saw not 600, but 500 of those merge with India. "Only one (kingdom) he could not carry through, he although got the king to sign, but Mr Jawaharlal Nehru took over, it was Kashmir. And that headache is still there. But am positive given the grit of Mr Narendra Modi, by 2019, we will have solved the Kashmir problem," Swamy said. Swamy made the remarks while delivering a talk on India in Global Economy during an event, organised in New Delhi by Delhi Study Group to felicitate the leader on his becoming a Rajya Sabha member.
