The German government has approved a Memorandum of Understanding for the sale of three submarines to Israel, Israeli sources have revealed.

The sources, who requested anonymity due to the political sensitivity of the matter, said that the MoU is likely to be signed by both sides in the coming weeks, despite an ongoing investigation into the matter.

Israel's Yedioth Ahronoth reported on Friday that in the framework of the revised MoU, Germany has reserved the right to stop the deal and even cancel it if the investigation that is currently under way in Israel at any point will reveal that senior officials who undertook the deal did so unlawfully.

Dubbed Case 3000, the probe is investigating possible wrongdoing involving Netanyahu's personal lawyer and German shipbuilder ThyssenKrupp's local representative as part of the 2 billion Euro deal whereby Israel is to purchase three submarines and four patrol boats intended to protect Israel's offshore natural gas platforms. Germany had postponed the signing of the memorandum in June, in light of the investigation.
