Union minister Anurag Thakur on Monday attacked Aam Aadmi Party chief Arvind Kejriwal, saying he talked big on corruption before entering politics but now several leaders of his party are in prison for graft.

Speaking to reporters here after a meeting of BJP functionaries of the Hamirpur Lok Sabha seat, he also targeted the Mamata Banerjee-led Trinamul Congress over the recent attack on Enforcement Directorate (ED) staff in West Bengal.

The Union information and broadcasting minister said it has become a habit of the Trinamul Congress to question constitutional institutions and sometimes, even attack independent investigative agencies.
