The recommendation to deny the pardon was made by professional staff at the Ministry of Justice and Minister Ayelet Shaked is expected to relay the recommendation to Rivlin.
Olmert was originally sentenced to six years over the Holyland bribery scandal, which was eventually decreased to 18 months following a successful appeal. However, Olmert was also sentenced to another eight months was tacked on to his sentence over the "Talansky" affair.
If the clemency request is granted, Olmert could possibly be freed immediately or have his sentence reduced by a certain amount. With the expected denial of clemency, Olmert is set to be released from prison in July.
Rivlin is expected to make his decision within a month.
