The Delhi high court on Tuesday deferred till tomorrow the hearing on the bail plea of Rajya Sabha MP Amar Singh, arrested for his alleged role in the 2008 cash-for-vote scam.

Justice Suresh Kait decided to hear Singh's interim as well as regular bail pleas tomorrow at 2.15 PM after the state counsel sought an adjournment due to non-availability of its senior advocate to advance arguments on its behalf.

Singh moved the high court after a city court had on September 28 rejected both his interim and regular bail pleas, saying his role was "major" in the entire episode aimed at "disgracing" parliamentary democracy.

The All India Institute of Medical Sciences (AIIMS), where Singh is admitted, had on October 12 submitted his medical report in the court saying that he needs constant medical monitoring.

"He needs to be constantly monitored for renal function, infections and if he is travelling he should be under the supervision of a nephrologist, a dialysis technician, a nurse and use ambulance/air ambulance for emergency," the report by additional professor Doctor Sanjay Gupta of the AIIMS' department of nephrology, had said.

The former Samajwadi Party general secretary was arrested on September 6 after he appeared before the trial court in response to summons for his alleged involvement in the scam.

He was taken to AIIMS from Tihar Jail on September 12 after a bout of vomiting and diarrhoea. He was granted interim bail on September 15.
