Sacked Delhi minister Kapil Mishra has said he will expose Chief Minister Arvind Kejriwal's biggest lie with evidence at a press conference scheduled to be held later today.

Mishra, who was sacked by Kejriwal after he alleged corruption in the Aam Aadmi Party (AAP) and claimed that all was done under Kejriwal's knowledge, said he will expose hawala links with AAP leadership.

"I will be revealing a big truth at 11 am with evidences. The expose will again prove their nexus with hawala operators," Mishra said in a series of tweets.

The former Delhi water supply minister's tweets regarding his new expose came after a businessman ribbished his claims corruption in AAP.

The businessman claimed that he had donated Rs 2 crore to the AAP, rubbishing Mishra's allegation that the amount was paid by a shell company.

Mukesh Sharma, a property dealer and tobacco trader, said he had donated the money through a demand draft on March 31, 2014.

"The public support to the AAP at that time was over-whelming and I had donated the money to the party hoping that it will do good for Delhi and for the nation," Sharma said.

Mishra had earlier alleged "massive irregularities" in the funding of the AAP and raised questions about the "suspicious" donation of Rs 2 crore.

He had also claimed that several shell companies had given money to the AAP and the party knew it.
