"However, a very strong electoral alliance will emerge in the state under BJP's leadership," he told PTI.
He welcomed the efforts taken by Gandhian leader Tamilaruvi Manian for forming a grand alliance in the state with the BJP at the centerstage.
Hitting out at the UPA Government, he alleged it had failed in all respects.
Radhakrishnan criticised the Tamil Nadu Government for "not taking effective steps" to increase power production in the state.
Referring to the treatment meted out to Indian diplomat Devyani Khobragade in the US, Radhakrishnan called for stern action from the Indian Government.
"In the past, when incidents like frisking former President Abdul Kalam happened in the US, India did not react properly. At least now, the Government should wake up," he said.
