The future of Wembley’s bid to host the first UK supercasino has been thrown into doubt after the new leader of Brent Council reportedly said that the majority of the council would not back the proposal.

A condition of the supercasino bidding process is that the relevant local authority is willing to licence the site, so without the council’s backing, Wembley would effectively be forced out of the running.

The scheme – which was recently shortlisted by the Casino Advisory Panel (CAP) alongside Greenwich, Cardiff, Glasgow, Newcastle, Manchester, Blackpool and Sheffield – was backed by the Labour-run council, but the local authority is now under Liberal Democrat and Conservative leadership and the council’s executive is set to review the supercasino proposal.

A spokesperson for the council said: "Brent Council has not made any decision. We have not withdrawn our bid. A report will be going to the new executive over the summer for their consideration.

"The new administration, formed on Monday 26 June has not yet had an opportunity to consider the options."

A decision is expected in September.

According to the London Evening Standard, however, the council’s new Liberal Democrat leader, Paul Lorber, has claimed that a Las Vegas-style casino is ‘wrong’ for a residential area like Wembley and said that the majority of the new council is not in favour of the scheme.

The proposal is a joint venture between developer Quintain and US-based gaming group Caesars and would see the creation of a £335m ($600m), 650,000sq ft (60,400sq m) resort called Caesars Wembley.

As well as a luxury casino, the resort would include a 400-room luxury hotel, convention space, a spa and swimming pool and a selection of restaurants, bars and lounges.

The government is currently allowing the building of just one supercasino, which will have a minimum customer area of 5,000sq m (53,800sq ft) and be allowed 1,250 gaming machines with unlimited jackpots.

Twenty-seven towns and cities originally made bids for the regional casino at the end of March this year.

Forty-one other councils applied for licences to run one of the eight large and eight small casinos, which will only house gaming machines with limited jackpots of £4,000 and have smaller gaming floors.

Successful applicants making the shortlist for smaller casinos include Milton Keynes, Brighton, Leeds and Middlesborough.

CAP will deliver its final decision on all three types of casino to culture secretary Tessa Jowell at the end of the year. Details: www.culture.gov.uk/cap
