The ICJP also sent photographs of brochures and leaflets advertising property in illegal settlements from Sunday’s event to London’s Metropolitan Police.
MEE has contacted the Charity Commission for comment.
The Metropolitan Police are not investigating the event, MEE understands.
The government said last week it would “explicitly advise businesses against economic and financial activity in illegal settlements”.
MEE has attempted to reach the real estate event’s organisers for comment.
The Edgware United Synagogue has also been contacted for comment about the event but has not responded.
Organisers denied last week in comments to Jewish News that the event would feature land for sale in the occupied West Bank, saying: “All exhibitors, without exception, will provide information about properties and projects within the Green Line.
“We believe that these ridiculous allegations are motivated by anti-Israeli and terrorist supporters, seeking only excuses to attack Jews in general and the State of Israel in particular.”
