New Delhi, Jan 28 (IANS): Aam Aadmi Party (AAP) chief Arvind Kejriwal Wednesday said the opposition parties would make "a last ditch attempt" to malign his party by planting false stories in the media.

He appealed to the people not to believe any false story ahead of the Feb 7 Delhi assembly polls.

"We have got information that opposition parties will level false allegations against some candidates of the AAP in the next few days," the former chief minister told reporters here.

He cited a sting operation against six AAP candidates in the run-up to the 2013 assembly polls, which he said, had turned out to be false.

He said AAP's rising support and TV channels' surveys showing the AAP being the favourite to form the government in Delhi had "unnerved the opposition parties".

"A very senior leader is known for planting stories in newspapers and television channels. He has been tasked to do so. He will plant some stories. I will appeal to the people of Delhi not to believe any stories. This is their last ditch attempt to malign the AAP," Kejriwal added.

Kejriwal also said that a CBI inquiry should be ordered against AAP candidates if the opposition parties had any evidence.
