Israel's Justice Minister Tzipi Livni has been granted diplomatic immunity for her visit to London this week, the Foreign Office has confirmed.
Ms Livni's trip has been awarded "special mission status", offering protection against the threat of arrest or prosecution.
Anti-Israel groups had again threatened to apply for an arrest warrant for Ms Livni, claiming she should be prosecuted for war crimes for her role in Israel's 2009 Cast Lead operation in Gaza.
A Foreign Office spokesman said: "Since the visit meets all the essential elements for a special mission, and for avoidance of any doubt on the matter, the FCO has confirmed consent to the visit as a special mission."
