No politician being tailed: PMO

The Prime Minister's Office on Thursday denied that several prominent figures, including politicians, have been put under surveillance.

"These reports are baseless, wholly fabricated, factually incorrect and mischievously speculative. These have, therefore, no basis in fact," Sanjay Baru, media advisor to the PM, said in a statement in New Delhi.
