This is a controversial subject and Wikipedia ought not to be used for POV or Promotional purposes to promote ANY political party. Prashant Bhushan (the AAP's co-founder) intervened in the BJP's Writ Petition filed through their councillor Nand Kishore Garg where this "demand" for CAG audit of discoms was made. The case was decided in 2011, the Court rejected the demand for CAG audit, nobody appealed this decision and it is final and binding. From Oct 2012 onwards when the AAP went political they made a series of defamatory statements about electricity sector which have all now been withdrawn from AAP's website. Many of these  old news reports refer to those AAP withdrawn statements, should they reenter Wikipedia through the backdoor of outdated sources ?  To answer your point - the AAP today (2013) is supporting BJP's demand, it is not AAP's demand for CAG audit. Both those sources say BJP and AAP are asking for CAG audit
