Israeli Prime Minister Ariel Sharon has left hospital two days after suffering a minor stroke. Joking with reporters outside Jerusalem’s Hadasa hospital, he said: “Now I must quickly get back to work and move forward. It appears that you have missed me.”The 77-year old leader is gearing up for his campaign ahead of a general election on March 28, the first for his new Kadima party. Doctors say his stroke has not caused any damage and is unlikely to recur, but have advised Sharon – whose appetite is legendary – to lose weight. It is not thought his health problems have influenced voters ahead of the election – according to opinion polls published today, Kadima would pick up around twice as many seats in parliament as the ruling Likud.
