Just in: The Supreme Court has slapped a notice against Delhi CM Arvind Kejriwal, and AAP members Manish Sisodia, Prashant Bhushan and Shazia Ilmi on the basis of a defamation complaint filed by Kapil Sibal's son.

Kejriwal had attacked the Law Minister over the Vodafone tax case and said all the corrupt ministers have joined the Group of Ministers on CBI autonomy. "Kapil Sibal says he will sort out the tax liability on Vodafone and Hutchinson in an outside court settlement. We have learnt that Kapil Sibal's son is a Hutchinson's lawyer," Kejriwal had said.

"The question arises whether a portion of Rs 2,000 crore has gone to Sibal."

Prashant Bhushan had noted that Hutchinson was bought by Vodafone in 2007 and most of it was done on capital gains. Vodafone is facing the tax liability of over Rs 11,217 crore for purchase of Hong Kong-based Hutchinson Whampoa's stake in Indian telecom business Hutchison Essar in 2007.
