Las Vegas Sands, the casino operator controlled by billionaire Sheldon Adelson, has received a boost after its bankers agreed to amend a $3.3bn credit facility, allowing it to spin off its Macao operations.

The company, which is considering a Hong Kong initial public offering of its Macao assets, said the amendment permitted it to sell a minority interest of the businesses, while $500m of the proceeds must be used to repay debts.
