Prime Minister Ehud Olmert should suspend himself immediately, Labor MK Shelly Yacimovich told Israel Radio, Friday. Yacimovich was responding to news that police were given permit to summon Olmert to an immediate investigation. "Olmert is stuck up to his neck in investigations. We cannot have a prime minister who is serially investigated by police. He is plainly corrupt even without [the public] waiting for a conviction. "In the entire world there was never yet a precedent of a prime minister against whom so many investigations were held," Yacimovich said.
