New Delhi, Nov 27 (ANI): Aam Aadmi Party leader Arvind Kejriwal will host diamond merchants, Bollywood artists and bankers for a 'Rs. 20,000 per plate' dinner next week in Mumbai, kick-starting AAP's fund-raising campaign for the upcoming assembly elections in Delhi. Reacting over this, the BJP on Thursday slammed AAP and said that the party has destroyed its credibility and people have no faith in AAP.
