In another setback to Bihar's ruling Janata Dal-United (JD-U), its sitting MP Vishwamohan Kumar from Supaul seat quit the party and joined the BJP Sunday.
Vishwamohan was upset after he was denied ticket to contest the Lok Sabha polls.
After joining the Bharatiya Janata Party (BJP), Vishwamohan blamed Bihar Chief Minister Nitish Kumar for denying him ticket to fight the elections.
Another JD-U legislator Annu Shukla Sunday revolted against the party and threatened to contest from Vaishali seat as Independent.
"I will contest the polls as Independent after being denied a party ticket," said Annu, wife of criminal-turned-former MP Munna Shukla, who is behind bars in connection with a murder case.
Three days ago, former JD-U Rajya Sabha MP N.K. Singh resigned from the party and joined the BJP. A former bureaucrat, Singh was unhappy after JD-U did not renominate him for the Rajya Sabha.
