An investigation published on Thursday by Shomrim and the International Consortium of Investigative Journalists (ICIJ) found that Iran’s new supreme leader, Mojtaba Khamenei, acquired luxury properties in London using a loan provided by a company owned by British-Israeli businessmen.

According to Shomrim, the loan was arranged by the British investment group TOPLAND, which was founded by Israeli brothers Sol and Eddie Zakai, The Caspian Post reports, citing The Jerusalem Post.

The investigation said that in 2013 a loan of approximately £36 million was granted to Khamenei through a company registered in the Isle of Man, a well-known tax haven. At the time of the transaction, there were no sanctions imposed on the individuals or entities involved, the report noted.

Currently, Khamenei is said to control a financial empire worth at least $3 billion in London, Britain, the UAE, and several other European countries, in addition to Iran, yet none of these assets appear in his name on official ownership documents.

Ali Ansari, an Iranian businessman, is Mojtaba Khamenei's agent for property acquisitions and investments.

Ansari’s reported dealings in Europe ended last October when British authorities sanctioned him and froze his assets.

Germany and Canada also opened inquiries into Ansari following a Bloomberg investigation released earlier this year that detailed his dealings with the Iranian regime. However, Ansar contested the report and claimed he had no connection to Khamenei.
