The Government have signed financial guarantees of £300million for England's hosting the tournament and made other commitments regarding security, visas and tax.

The agreements have been signed several months ahead of the May deadline, and Sutcliffe said that was a sign that, after a period where the bid board was riven by disagreements and criticism, unity has returned to the campaign.

Sutcliffe told Press Association Sport: "It is now united, and the guarantees combined with our offer of a £2.5million loan which is on the table if they want to pick it up, underlines that.

"I think the board moves were right and my concern now is that football will deliver us this bid, as they have to get the votes of the 24 FIFA executive committee members.

"Signing off the guarantees at this early stage puts the bid in good shape."

The guarantees have been agreed by all political parties and signed by Prime Minister Gordon Brown and other ministers from relevant departments.

Sutcliffe added that it was important to have the commitments in place before the general election next year.

The minister said: "What's important to me is that we kept the pressure on and managed to get all the departments to agree very quickly.

"It does have all-party support for these are substantial costs for the future, but the World Cup would, of course, also bring huge economic benefits to this country.

"My view also was that we wanted this done before Christmas and certainly didn't want it to run into any problems with a general election when so much else would be happening."

FIFA oblige bidding nations to sign a confidentiality clause so the exact details of the guarantees are not being released.

It is likely that the tax guarantee is similar to the deal the Government agreed with UEFA in order to stage the 2011 Champions League final at Wembley, where foreign players will be exempt from being taxed on their tournament earnings.

England bid chairman Lord Triesman said it would be impossible to host the tournament without such commitments.

He said: "The signing of the guarantees months in advance of the May 2010 deadline is a testament to the Government's commitment to bringing the World Cup to England, in particular the sports minister Gerry Sutcliffe and his officials who have worked very hard to secure them so early.

"The guarantees underpin around £300million worth of financial commitment without which it would be impossible to host the tournament.

"This again demonstrates England's desire as a whole to meet and exceed FIFA's requirements and guarantees FIFA the most secure environment possible for the world's biggest sporting event in terms of security, financial, legal and commercial partner delivery."

England 2018 will tomorrow announce which of the 15 cities will be part of their bid. Around 12 cities containing up to 18 stadiums are expected to be named.

The cities in contention are: Birmingham, Bristol, Derby, Hull, Leeds, Leicester, Liverpool, London, Manchester, Milton Keynes, Newcastle/Gateshead, Nottingham, Plymouth, Sheffield and Sunderland.

An England 2018 delegation led by Triesman and former Manchester United striker Andrew Cole today made a formal presentation to FIFA executive committee member Amos Adamu in Abuja, Nigeria.

The presentation included personal messages of support for the bid from Nigeria captain Kanu and Chelsea midfielder John Obi Mikel.

During the meeting, Adamu, a United fan, also watched a specially-prepared film of the final two minutes of the famous 1999 Champions League win over Bayern Munich, narrated by Cole.

Triesman said: "We are enormously grateful to Dr Adamu for giving us the opportunity to discuss our bid with him as it has helped us further develop our understanding of what we need to do to stage a tournament that would be good for the game all over the world."

The bid delegation also visited Abuja Children's Home, where Cole took part in a coaching session with the youngsters.
