Middle East Eye is publishing photos of brochures and leaflets at the event which advertised property in occupied Palestinian territory and promoted companies with links to illegal settlements.
The revelations come as British Foreign Secretary Yvette Cooper announced that ministers have asked the Advertising Standards Authority to investigate the Great Israeli Real Estate Event which took place on Sunday.
On Monday, Middle East Eye revealed details of properties advertised in illegal Israeli settlements at the event, which was held at the Edgware United Synagogue.
This comes as the Edgware United Synagogue has been referred to Britain's charity regulator for hosting the event.
On Monday the International Centre of Justice for Palestinians (ICJP), a UK-based legal group, submitted a formal complaint to the Charity Commission.
