In a fresh setback for Chief Minister Arvind Kejriwal ahead of the Lok Sabha elections, his private secretary has been sacked over alleged violation of rules during his appointment. Bibhav Kumar's services have been terminated with immediate effect, said the Directorate of Vigilance in its order, stating that he was appointed in violation of the Central Civil Service Rules, related to temporary appointments. The AAP hit back at the Lieutenant Governor over this latest setback and accused the BJP of trying to finish the party led by Mr Kejriwal.
