Israel is increasingly becoming a flashpoint for clashes over who dictates the EU's foreign policy between the bloc's top diplomat, Kaja Kallas, and the rest of the Commission, undermining its overall coherence.

On Monday, Euronews revealed that Dubravka Šuica, the European Commissioner for the Mediterranean, was travelling to Israel.

The Commission's spokesperson later said the trip had been long in the making, but it had not been announced on the Commissioner's dedicated webpage, and caught several European capitals off guard.

Chief spokesperson Paula Pinho could not explain why the trip had not been properly communicated, saying only that "they will look into that."

The trip came right after Israel's foreign minister, Gideon Sa'ar, severed all contact with Kallas, following media reports alleging she had compared the country to apartheid-era South Africa.
