Ahmedabad, Mar 12 (ANI): Congress leader Ahmed Patel on Saturday said that the government needed to focus on Vijay Mallya and ensure that the businessman returned to the country to join in the investigations on him. He said it was the responsibility of the government to tackle such issues instead of blaming the opposition. The Congress leader asserted that the BJP-led NDA Government should also take cognizance of many other issues which are going on in the country at the moment.
