Delhi Lieutenant Governor VK Saxena today said the national capital is fully prepared to host world leaders in the G20 Summit to be held on September 9 and 10. He said the city has been swept clean to present its best. He denied allegations that only areas that are likely to be seen by visiting leaders have been beautified. "Security has been increased and tightened. The entire Delhi won't be shut down," Mr Saxena told NDTV. On who should take credit for the work that's gone behind the G20 preps, he said he has done a lot of work on the ground. "If someone takes credit, I am glad I have done my work well," he said.
