In March 1945 Gaitskell suffered a coronary thrombosis brought on by overwork. Advised to rest, he considered withdrawing from his parliamentary candidacy in Leeds, but he was popular with his constituency workers and they offered to campaign for him even if he was unable to do so. He was also approached to return to UCL as a Professor after the war, but he disliked the constant state of flux of academic economics and the increasing emphasis on mathematics, a subject of which he had little knowledge. By now he found himself more drawn to public life.
