The expenses made to renovate Delhi Chief Minister Arvind Kejriwal's bungalow will be probed by the country's top auditor, sources said today, after a months-long controversy. The Union Home Ministry has ordered the audit following a letter from Delhi's Lieutenant Governor VK Saxena alleging gross irregularities, sources said. Denying allegations of irregularities, Mr Kejriwal's Aam Aadmi Party has accused the Centre of targetting political opponents.
