Former US president Barack Obama is to make his first visit to Scotland when he addresses business leaders in the capital next month.
He will also answer questions from the audience at the event, which is being held to raise money for charity.
The dinner in Edinburgh on 26 May is thought to be one of his first major addresses since his term as president came to an end.
The event at the EICC is being organised by The Hunter Foundation.
The charity was set up by leading businessman and philanthropist Sir Tom Hunter.Tickets for a table of 10 at the dinner are expected to go on sale for approximately £5,000.£500 a head? They could quadruple that and the EICC would still be packed to the gunwales.
