New Delhi, Feb 03 (ANI): Bharatiya Janata Party questioned the source of Aam Aadmi Party's funding, alleging that AAP accepted black money, ahead of Delhi polls. The BJP alleged that shell companies were created to transfer rupees 20 million to the AAP on April 05, 2014, while official records pointed that these companies didn't make any profit and had common directors. The BJP further added that AAP circumvented Indian laws to accept donation from foreign company. But the party was silent on initiation of probe against the AAP. Meanwhile, AAP leader Yogendra Yadav asked the central government to initiate investigation into allegations. Delhi goes to polls on February 07 for the second time in 14 months after AAP chief Arvind Kejriwal resigned as Delhi Chief Minister in February 2014 after being 49 days in power.
