Olmert was convicted on March 31 on two counts of receiving bribes in connection with a sprawling Jerusalem property development, in one of the biggest corruption scandals in Israeli history.
"The state is intending to seek five to seven years of prison time for Ehud Olmert for the first count and between two and four years for the second," a source at the justice ministry told AFP after sentencing deliberations got under way at Tel Aviv District Court.
In 2010, Olmert was named the key suspect in the so-called Holyland affair on suspicion that he received hundreds of thousands of shekels for helping developers get a massive residential construction project past various legal and planning obstacles.
Following a two-year trial, he was convicted of receiving bribes to the tune of USD 160,000 at the current exchange rate) with the judge also saying he had committed perjury.
The 68-year-old has vowed to appeal.
The sentencing process which began today is likely to last several weeks, legal sources said.
He was fined USD 19,000 and given a suspended jail sentence for graft.
