Former foreign minister Avigdor Liberman vowed over the weekend to leave politics if he is convicted in his ongoing corruption trial.The trial is expected to be completed in July and a verdict given by October. In an interview with Yediot Aharonot, he said he wants to be cleared of the charges against him, but he did not sound like a conviction would upset him. "I make tough decisions easily," he said. "I can very easily decide to leave politics. I never thought I would be a Knesset member. I was not born a minister and I don't have an obsession to stay in politics. If I'll be convicted, I will do what a fair person must do."When asked what he intended to do following his political career, Liberman joked that he intended to become a professional tennis player.
