A Birmingham MP is supporting Blackpool's bid for Britain's first regional super-casino.
Lynne Jones (Lab Selly Oak) said the seaside resort was a better location than either Birmingham or Solihull.
She disputed claims a casino would boost local economies, arguing it would simply divert income from other businesses.
City MPs were split over whether Birmingham should bid for a licence for a regional casino, as the council cabinet prepares to discuss the issue on Monday.
Birmingham City Football Club, which wants to build a casino in Saltley, has taken part in a bitter war of words with the NEC, which hopes to bring the casino to Solihull.
But Dr Jones said: "I don't think casinos are good for the economy. The profits go to the casino operator, which will be an American firm, and it is money that would have been spent in other ways if the casino wasn't there.
"The same is true for jobs. It would employ people, but it will redistribute jobs rather than creating new ones.
"If there has to be a huge casino than Blackpool is perhaps the most sensible place.
"People can go there for a weekend and blow some money, but not have the temptation on their way home from work every day."
A recent inquiry commissioned by the Office of the Deputy Prime Minister warned building new casinos could result in "enhanced socio economic problems in terms of crime, anti-social behaviour and potentially alcohol".
A number of MPs are supporting the Birmingham City proposal, including Khalid Mahmood (Lab Perry Barr), Steve McCabe (Lab Hall Green) and Roger Godsiff (Lab Sparkbrook and Small Heath).
Mr Godsiff said: "Birmingham City Football Club have come up with a very imaginative and exciting scheme.
"It will take an area of contaminated wasteland, which has basically been ignored, and decontaminate it. There will be a major stadium with a super-casino attached, with walkways and cafes."
But Clare Short, the MP whose constituency includes the site of Birmingham City's proposed casino, said she was "violently opposed" to the proposals.
Ms Short (Lab Ladywood) said: "It is very strongly opposed by local people. Gambling is an addiction that ruins lives and families."
Gisela Stuart (Lab Edgbaston) said she was backing the NEC proposal.
She said: "If we have a casino, the purpose will be to raise money for regeneration. So it makes sense to put the casino where it will make the most money.
"That means the NEC, with its conference trade and steady stream of visitors."
