Arvind Kejriwal, a core member of Team Anna, has run into legal trouble for comparing MPs to rapists, murderers and looters.
Sajjan Singh Verma, a Congress MP from Madhya Pradesh, has served a Breach of Privilege notice against Kejriwal for making derogatory remarks on MPs during an election rally in Ghaziabad last month.
The Lok Sabha Secretariat has sought for reply from Kejriwal following the notice.
Kejriwal, who has been closely working with social activist Anna Hazare, was earlier served a notice for making derogatory remarks against the Parliamentarians.
