All 40 candidates of the Aam Aadmi Party (AAP) for the upcoming Goa Assembly polls on Wednesday signed affidavits promising that they will not indulge in corruption or defect. “The biggest problem with Goa's politics is the frequent defections. We want to weed it out even before people vote for our candidates,” AAP convener and Delhi Chief Minister Arvind Kejriwal said addressing a press conference where all the 40 party nominees were present with their affidavits.
