New Delhi: Delhi Chief Minister Arvind Kejriwal slammed BJP-led Centre for not granting him the permission for attending the C-40 Climate Summit at Copenhagen, Denmark, which was scheduled for October 11.

The Ministry of External Affairs denied permission to an eight-member delegation led by Kejriwal to fly to Copenhagen to be part of the event, saying that clearance from "political angel" has been denied and the conference is meant for Mayors, not for Chief Ministers.
