The National Exhibition Centre is reconsidering ambitious plans to site one of the Government's super casinos at the complex following a change in the proposed gambling legislation.
A spokesman for the NEC yesterday said bosses were looking at the "fine detail" of the Government's announcement that there would be only one super casino in the UK.
Concerns were raised by the Solihull-based exhibition centre after Birmingham City Football Club boss David Sullivan yesterday aired his worries in The Birmingham Post about the Government's plans.
Culture Secretary Tessa Jowell said on Tuesday there would only be one super casino instead of the eight previously planned by Ministers.
Ms Jowell accepted the concession with the Tories to get the Bill through Parliament before it is dissolved for the General Election.
The NEC announced last summer it intended to include proposals for a super casino, which operates under relaxed gaming laws, in an 800,000 sq ft £300 million complex earmarked for the site.
However, a spokesman said last night: "We are looking into the fine detail of this latest announcements and we are considering our options."
Mr Sullivan raised concerns that plans for Blues' new super stadium hung in the balance as the project depended on funding from an American casino giant. Blues intend to build a 60,000 seater stadium on a 50-acre site in Saltley, anchored by a casino.
But the club's managing director Karren Brady yesterday insisted the club was optimistic its plans would eventually get the go-ahead.
She said: "Only one casino will be granted before the General Election but a new Parliament can vote on up to a further seven casinos without having to pass a new Bill.
"So it's not actually bad news, it's more a case of a delay."
Coun Ken Hardeman (Con Brandwood), the city council's cabinet member for regeneration, also remained optimistic.
He said: "It looks as if there is still a good chance that there will be several casinos.
"There could be something really positive on that site we have identified in Saltley."
