Lok Janshakti Party (LJP) chief Ram Vilas Paswan is in the Intensive Care Unit of a private hospital in Delhi after suffering a heart attack last night.
Doctors attending to Mr Paswan say that the Rajya Sabha MP from Bihar is stable.
"He is absolutely fine and speaking and will be released in a day or two. There is nothing to worry," Dr Vijay Kumar, senior consultant, intervention cardiologist, who is attending to him, told Press Trust of India.
The 67-year-old former Union minister, who concluded his three-month long Bihar Bachao Yatra on April 14, was rushed to hospital after he complained of breathlessness.
