The EU foreign affairs chief has been seen as indulgent of Israel and is locked in a power struggle with Ursula von der Leyen

It has played badly in Berlin, but the diplomatic spat between Kaja Kallas and Israel might well end up playing in her favour.

The EU foreign affairs chief has been widely viewed as soft on Israel. But in recent weeks, that perception has begun to change, in no small part due to a row between her and Tel Aviv that exploded into the open as she was celebrating her 49th birthday in Brussels.

Gideon Sa’ar said he was cutting off all ties with the Kallas on Thursday, six days after Euractiv revealed she had likened Israel’s treatment of Palestinians to South African apartheid.

When asked about her stance on ‘apartheid’ in the West Bank at Thursday’s European summit, she refused to comment on remarks she made behind closed doors.
