New Delhi, Nov 11 : The government is investigating the source of foreign funding to the Aam Aadmi Party (AAP), union Home Minister Sushilkumar Shinde said Monday.

“We have got complaints about foreign funding to AAP and are probing the matter... Investigations take time and we are looking for the source behind the funding,” said Shinde.

AAP's chief ministerial candidate Arvind Kejriwal, however, said the "funds of Congress and BJP (Bharatiya Janata Party) should also be probed".

AAP leader Kumar Vishwas challenged the government to prove them guilty.

“There’s no point in making allegations against us. I challenge both the Congress and the BJP to prove us guilty. We receive all our funds in a transparent manner,” he said.

“Both the parties are sacred of us,” he added.

The debutant AAP appears to have dimmed the prospects of both the Congress, which has been ruling Delhi for the past 15 years, and the opposition BJP which hopes to gain from a strong anti-incumbency factor.(IANS)
