KERALA: Calling the electoral bonds the “biggest haftebaazi” scheme, Congress leader Rahul Gandhi on Tuesday questioned as to why the names of donors were kept hidden by the ruling BJP government if the scheme was meant to ensure transparency in the election process. “This (electoral bonds) is Narendra Modi’s master scheme. The whole idea was his. He said the electoral bonds were launched to bring transparency in politics. Then, why were the names kept hidden? Who was stopping the release of data after the Supreme Court asked? This is extortion. On street level, it is known as ‘haftebazi’. This is the country’s biggest ‘haftebaazi’ scheme conceptualised by the Prime Minister,” Rahul Gandhi told reporters in Kozhikode.
