Robert Vadra has said he has developed a tumour in his large intestine.

Robert Vadra has submitted a medical certificate in court to say that he has a tumour in his large intestine and needs to travel to London for treatment. He had earlier appealed before the ED to seek permission to travel abroad.

On Wednesday, Vadra appealed that his passport be released so that he can travel to London for diagnosis and further treatment.

However, the Delhi court has reserved its order for June 3 on Robert Vadra's application to travel abroad.

During a hearing of his appeal to fly abroad, Robert Vadra submitted a medical certificate from Delhi's Gangaram Hospital that he has tumour in his large intestine.

The hearing took place at a special CBI court on Wednesday when Vadra's lawyers submitted his claims.

Vadra's lawyer KTS Tulsi argued in court that he has been taking part in the investigation at every occasion and that he returned to India without any summons being issued to him.

Tulsi further argued that it cannot be said that Vadra will flee investigation, which is why he should be granted permission to fly abroad for treatment.

Rejecting Vadra's claims, the prosecutor lawyer fighting for the Enforcement Directorate (ED) argued that the medical certificate bears the date of May 13. He asked, why the certificate was not submitted earlier.

The lawyer also argued, "Why does the medical certificate say he will take further opinion from London? He can take it from anywhere else. It's not like treatment is not available in India. Why is the medical certificate specifying where he can get the second opinion from?"

Vadra, facing investigation in a case under the Prevention of Money Laundering Act (PMLA), was directed on April 1 not to leave the country without prior permission by a court which had granted him anticipatory bail while imposing several other conditions.

Meanwhile, the ED has issued fresh summons to Robert Vadra to appear before it on Thursday in connection with a money laundering case linked to purchase of alleged illegal assets abroad.

They said Vadra has been asked to depose before the investigating officer of the case at around 10:30 am at the agency's office in New Delhi.

The ED only last week moved a court seeking cancellation of the anticipatory bail given to Vadra in this case and the Delhi High Court had then issued notice to him seeking his response.
