|ESPNsoccernet: World Cup 2010|
FIFA have told England and other nations bidding for the 2018 and 2022 World Cups they must demonstrate the tournament would lead to positive change for football.
The game's world governing body have kicked off the 24-month campaign by sending out a circular letter to all member associations eligible to bid inviting them to bid for either or both tournaments.
However, no country will be considered for 2022 if another nation from their continent wins the vote for 2018.
The letter reads: "FIFA is determined that this overwhelming ability to reach out to the world should benefit the game of football itself and society in general, and therefore asks that candidates make sure that this power is used in order to achieve positive change.''
The letter states that around 12 stadia with a minimum capacity of 40,000 will be needed to host the tournament. The stadium for the final will have to have at least 80,000 seats - Wembley has 90,000.
It adds: "FIFA would like to emphasise that the infrastructure and facilities of the host country must be of the highest quality in order to fulfil the requirements of the world's most popular sporting event.''
The letter confirms African and South American nations cannot bid for 2018, and South American countries may not bid for 2022 either as South Africa are 2010 hosts and Brazil are 2014 hosts.
FIFA also released a timeline of the bidding running up to the decision in December 2010.
The timeline is:
• February 2: Deadline to submit expression of interest letter to FIFA.
• February 16: FIFA send bid registration form to those associations who have expressed an interest.
• March 16: Deadline to complete registration form and provide any other documents required by FIFA.

• May 14, 2010: Submission to FIFA of the bid book and the signed hosting agreement.
