"Well it is a great compliment to RSS that the movement against corruption was sponsored by RSS," Swamy told reporters here when referred to Singh's comments.
"...He doesn't know what he is saying. He is actually praising RSS. May be he wants to join us," he added.
Swamy also slammed Singh for his comments that AAP is the 'B Team' of BJP and that Congress had "chosen a lesser evil" by supporting Arvind Kejriwal in forming the government in Delhi in 2013.
He said these accusation will not have any effect and BJP's Kiran Bedi will become the next Chief Minister and restore law and order in Delhi "which had collapsed in the 49-day rule of Arvind Kejriwal".
