Las Vegas Sands, one of America's biggest gambling companies, is pressing for fresh amendments to the Gambling Bill following the Government's controversial decision to introduce a cap of eight mega-casinos.

The company, which owns The Venetian casino on the famous Nevada strip, has proposed four amendments which it believes will maximise the regeneration benefits, while reducing the scope for problem gambling.

The company has outlined plans to build mega-casinos, also known as "regional casinos", at Glasgow Rangers, West Ham United and Sheffield United football clubs.

Like the other major US players, Las Vegas Sands opposed the decision to cap mega-casinos during an undefined initial phase. They will have up to 1,250 slot machines with unlimited jackpots.

Richard Caborn, the culture minister, is expected to give an indication of how the cap may work at tomorrow’s committee hearing for the Gambling Bill, though few in the industry expect firm details. While he is most unlikely to name locations which will get licences, industry sources believe he may indicate how many will be built at inner city or seaside locations.

Las Vegas Sands' proposed amendments would raise the bar for entering the competition for the eight licences. It wants the minimum size of a mega-casino to be raised from 5,000 sq m to 7,500 sq m, with an obligation to provide at least 3,750 sq m of non-gaming space, such as hotels, bars and retail areas. This would raise the current minimum investment required from around £100m to £150m-plus.

The company also wants to see "an accredited policy for dealing with problem gamblers" to be a "precondition to obtaining a licence". A third amendment would allow local authorities to remove an operator's licence if it failed to provide agreed regeneration benefits for the local community.

Las Vegas Sands wants the Bill to ensure that licences for all smaller casinos are subject to a "separate planning use category" to prevent their proliferation. The Government has indicated it will do this but it does not yet feature in the Bill.

Rodney Brody, head of the company's UK operations, said: "We believe that these amendments will further strengthen the Bill."
