The Indonesian cigarette billionaire Putera Sampoerna has put Les Ambassadeurs, his high-rolling London casino, up for sale 18 months after buying it. A number of the world’s biggest gaming groups, including Harrah’s, are taking a keen interest, but it is thought that Las Vegas Sands is the frontrunner to buy it. However, the purchase price could be below the [[GBP]] 115m that Sampoerna paid. Les Ambassadeurs is one of London’s most exclusive casinos, attracting high rollers as well as a good smattering of hedge-fund managers, trustafarians and Premiership footballers.
