Israeli President Shimon Peres was discharged from hospital with a clean bill of health, a day after the 86-year-old Nobel peace laureate passed out briefly at a ceremony.

‘I can say to everyone that we have a president who is dynamic, young at heart and physically healthy,’ said Dr Zeev Rothstein, director of Sheba Medical Center near Tel Aviv where Mr Peres was kept for observation overnight.

Mr Peres fainted at the podium during a public appearance in Tel Aviv last night.

Doctors said he was apparently overcome by the heat.

He quickly regained consciousness after medics rushed to his side, but his personal physician, who is also his son-in-law, insisted he go to hospital.

Dr Rothstein told Israeli radio stations that tests showed that Mr Peres was in ‘excellent condition’.

He maintains a busy schedule that includes frequent speaking engagements in Israel and official visits abroad.

Mr Peres, whose role is ceremonial, was expected to resume much of his daily routine, including a planned meeting later today with US Middle East peace envoy George Mitchell.
