The designated Acting Prime Minister (, "Memaleh Mekom Rosh HaMemshala" lit. "Prime Minister's Place Holder", or "Prime Minister's stand-in") takes the role of Prime Minister as Acting Prime Minister, for up to 100 consecutive days, if the incumbent is "temporarily incapacitated". Whilst in other countries the term "Acting Prime Minister" only refers to an individual actually performing the role, in Israel the term is also in use when a designated minister is allocated, even if they never actually perform the role. The incumbent minister must be also a Knesset member to be eligible for this role.
