Israeli Prime Minister Ehud Olmert will on Friday be put on the grill by police for the fifth time in three months, local daily The Jerusalem Post reported Tuesday.

The questioning session, scheduled on Friday morning at Olmert's official residence in Jerusalem, will also mark the second police interrogation against the probes-laden premier since he announced that he would not contend in his ruling Kadima party's primary and would resign as soon as a new party leader was chosen.

The police has not specified on which case the investigators will concentrate on with Olmert, who is currently embroiled in two investigations, respectively over his alleged double-billing of sponsors for overseas trips and his alleged taking of illicit money in envelopes from an American businessman.

The prime minister, who also faces four other probes, has been facing mounting calls for him to step down since the "money envelopes" case went public in early May. He denied any wrongdoing and said he would resign if indicted.
