It may be the ultimate indiscreet lunch.

WikiLeaks is offering eight people the chance to dine with founder Julian Assange as a fundraiser for its secret-spilling work.

Bidding on auction site eBay started Monday at 350 pounds ($568) a head and had topped 500 pounds by Wednesday. Bidding closes Monday.

The site says guests will dine July 2 at "one of London's finest restaurants" with Assange and Slovenian Marxist philosopher Slavoj Zizek.

Later that day the pair are due to give a talk about WikiLeaks' impact.

U.S. authorities are investigating whether WikiLeaks broke the law by releasing thousands of secret government documents.

Assange is on bail in Britain as he fights extradition to Sweden on allegations of sexual misconduct against two women, which he denies.
