An official inquiry has been launched after Declassified revealed that an Israeli state-owned weapons firm had funded a group of British MPs.

RUK Advanced Systems Ltd sells weapons including urban combat missiles and “hard kill” torpedoes. But records show it is part of the defence giant Rafael, which is owned by the Israeli government.

Our investigation found the company had paid at least £1,499 to partner with the All-Party Parliamentary Group (APPG) on Defence Technology, which provides “opportunities to network with MPs”. The money was paid directly to the group’s secretariat.

But parliamentary rules say that APPGs should not “accept the services of a secretariat funded directly or indirectly by a foreign government”.
