Earlier on Wednesday, Israel's highest appeals court sentenced Shlomo Benizri, another former cabinet minister, to four years in prison for corruption, more than doubling the sentence he originally received for taking bribes.
"There is a phenomenon of increasing corruption in Israeli society ... the time has come for action"

The judges said they extended Benizri's sentence to set an example and to fight back against a tide of corruption in Israeli public life.
"There is a phenomenon of increasing corruption in Israeli society, to which the institutions of power have not been immune," the appeals judges wrote in a verdict, increasing the former welfare and health minister's sentence from 18 months.
"To address this scourge and act as a deterrent ... the time has come for action and to exact a higher price."
Benizri, a member of the Jewish ultra-Orthodox Shas party, was a minister from 2000 to 2003 in successive left- and right-led coalition governments.
