Egyptian lawyer Galal Abdel-Rahman has filed a lawsuit against right-wing MK Avigdor Lieberman.
He is furious that Lieberman allegedly insulted Egyptian president Hosni Mubarak. Last week, Lieberman said that Mubarak could "go to hell" because he refused to make visits to Israel.
Outgoing Prime Minister Ehud Olmert apologised for the "crude" comments .
