Fotis Kouvelis, the head of Democratic Left which quite the governing coalition in June, was taken to the capital's Geniko Kratiko Hospital on Friday after complaining of feeling faint at Athens International Airport where he had been due to board a flight to the northern city of Kavala.
According to sources, Kouvelis had come round by later on Friday morning, but doctors who gave him first aid treatment proposed that he undergo preventive medical tests.
Speaking to Skai, Health Minister Adonis Georgiadis said there was no cause for concern. Kouvelis' close associate Thodoros Margaritis gave the same message. «The doctors did not convey to us any serious concerns» he said.
