A senior party source told, "Vadra was admitted in hospital in Noida on Monday afternoon after he complained of severe back pain."

He is being treated by senior orthopaedic surgeons at the hospital, the source said.

His wife and Congress General Secretary Priyanka Gandhi Vadra visited the hospital and stayed there the entire night.

She left the hospital on Tuesday morning to leave for Rae Bareli, her mother's parliamentary constituency, to attend a three-day workshop with party workers that starts today.

Vadra, who is being probed by the Enforcement Directorate (ED) in money laundering case, had earlier gone abroad for treatment with the court's permission .
