"For nearly 40 years, casinos have been established by demand; you had to go to the magistrates and prove there was a demand for your business. Now it will just be a government decision.
"These super casinos will be supermarket money machines. They will need to get 20,000 people in a week and will probably have advertising budgets of £10m-£20m. It is something which could do enormous damage."
Mr Taittinger is angry that the super casinos will be allowed more gaming machines than current operators and believes the proposed legislation is simply not equitable.
"All we want is to compete on a fair playing field.
"I am allowed 10 slots, how could I compete with a super casino with 150 or more? In my view, the smaller casinos will die." It is thought that at least one super casino will come to the North West if the legislation is approved.
Blackpool wants to remarket itself as a casino resort - though it remains to be seen how many, if any, licences it will be awarded - while Manchester would be the obvious third option for a North West base.
The Leo already has planning permission to expand from 17,000 sq ft to 30,000 sq ft, but Mr Taittinger submitted options for a 100,000 sq ft super casino on his site to the council earlier this year.
It could create up to 1,000 jobs with bars, restaurants and a nightclub surrounding the casino.
That could involve an investment of "£50m-£100m, possibly more" according to the champagne magnate, though he hopes it will not happen.
"If the legislation is not completed by the time a general election is called, I believe it has to start its passage again and that is what I very much hope will happen," he said.
