Former Union minister Raj Kumar Singh, who has been in the news for his outbursts against the ruling NDA in Bihar, was suspended from the BJP for “anti-party” activities, a party leader said.
According to media reports, Singh, who has been served with a suspension order by the BJP headquarters in the state, has also been asked to show cause why he should not be expelled from the party.
In a similar action, the party also suspended MLC Ashok Kumar Agrawal and his wife Usha Agrawal, the mayor of Katihar, the BJP leader said.
R K Singh in post on X had had tweeted his resignation from the party in a letter addressed to party president J P Nadda

The couple had canvassed for their son Saurabh, who was contesting the Katihar assembly seat on a ticket of Vikassheel Insan Party, against sitting BJP MLA and former Deputy CM Tarkishor Prasad.
Singh, the bureaucrat-turned-politician, who joined the BJP in 2014, months after retiring as the Union home secretary, has been critical of leaders, like Samrat Choudhary, a deputy chief minister of Bihar and a former state BJP president, for their alleged involvement in criminal cases.
He failed to retain his Ara Lok Sabha seat for a third consecutive term in the Lok Sabha polls last year.
