New Delhi: Apparently sensing that the Congress is spent force and the real challenge in their march to Parliament comes from the BJP, the Aam Aadmi Party appears to be working on a structured plan to corner Narendra Modi.

And, leading the charge from the AAP is senior Yogendra Yadav. He has taken to Twitter to hit out at Narendra Modi on issues, which the AAP perceives are the BJP prime ministerial candidate`s soft spots.

Yadav sent out a series of tweets questioning Modi on the controversial murder of Gujarat BJP leader and former home minister Haren Pandya in 2003.

Yadav tweeted, "Who killed BJP leader Haren Pandya, Gujarat`s ex home minister? Will his family ever get justice after an 11-year wait? The high court overturned the conviction of those framed by the Gujarat Police. Why no re-investigation so far?"

The AAP , while it was in power in Delhi, had announced that launch of a "pol khol" campaign against the BJP and Congress to expose their "conspiracy" against the Delhi government.

Following the fall of the Arvind Kejriwal government, the BJP and the Congress announced their respective `pol khol abhinyan` to expose the anarchist ways of the AAP and to make Delhiites aware of the string of broken promises by AAP.
