Starehe parliamentary seat loser Steve Mbogo and his wife, Ms Sabrina Jamal, have sued blogger Cyprian Nyakundi for defamation.
Mr Mbogo says in the case filed in the High Court that unless Mr Nyakundi is stopped, he will continue publishing similar articles on social media.
"Our standing in society has been brought into disrepute by the articles published on social media by the defendant," the couple says in the petition before Justice Jaden Thuranira.
Justice Thuranira, who certified the case as urgent, directed Mr Nyakundi to appear in court by December 13, or else judgment would be entered against him.
The couple is seeking Sh20 million in damages.
They also want Mr Nyakundi restrained from publishing any more articles about them on social media and also to pull down those he wrote on November 28.
Through lawyer Velma Maumo, the two claim that Mr Nyakundi has continued to publish defamatory articles about them on various social media platforms, ruining their reputation and disparaging their marriage, family and integrity.
