New Delhi: Having ended her 32-year-long association with BJP, former Prime Minister Atal Bihari Vajpayee's niece Karuna Shukla on Thursday joined Congress and slammed Narendra Modi saying his promise of serving the country is nothing but "plain dishonesty".

Hitting out at Modi, Shukla said the BJP has declared such a person its prime ministerial candidate "who did not fulfill the duty of a husband or rajdharma when he was chief minister. If such a person talks about discharging rashtradharma, I will call it plain dishonesty".
