Lok Sabha Speaker Om Birla has referred BJP MP Nishikant Dubey's complaint against Trinamool Congress member Mahua Moitra to the Ethics Committee of the lower House.
Dubey had Birla to constitute an "inquiry committee" to look into charges against her.
Moitra has hit back, saying she "welcomes any move against her after the Lok Sabha Speaker is finished dealing with pending charges against him (Dubey)".
The Ethics Committee of the Lok Sabha is chaired by BJP member Vinod Kumar Sonkar.
