7. Branding Congress, AIADMK, DMK as corrupt, BJP prez Amit Shah seeks mandate for party: Attacking AIADMK, DMK and Congress for practising politics of "corruption", BJP chief Amit Shah today sought to pitch his party as an alternative in Tamil Nadu. He alleged that AIADMK and DMK, which have ruled the state for decades, have "pulled down" the development graph and urged the people of Tamil Nadu to vote for NDA to usher in politics of development. Addrressing an election rally here, Shah referred to various allegations of corruption against the two Dravidian parties besides BJP's arch-rival, Congress. He charged that DMK, AIADMK and Congress are "corrupt" and they do not "know anything other than corruption." "DMK (is facing allegations) in 2G spectrum allocation and Aircel-Maxis... how many scams are there against DMK," he said. Targeting senior Congress leader P Chidambaram, Shah said he and his son Karti "were also facing charges," in an apparent reference to the Aircel-Maxis deal. Shah, who had last month called the AIADMK dispensation the "most corrupt government in the country," referred to the disproportionate assets case against its supremo and Chief Minister J Jayalalithaa, now being heard in the Supreme Court. "In AIADMK, there is a disproportionate assets case against Jayalalithaa," he said. "The voters of Tamil Nadu have to decide in these Assembly polls if they wish to continue with politics of corruption and nepotism or they want to move to politics of development.
