England's Rugby Football Union's proposal to host the Rugby World Cup in 2007 contains a string of changes to the existing format.

Q: How will the World Cup, if hosted in England, work exactly?

A: A total of 16 teams will play in four pools, with the top two teams from each pool qualifying for the Super Eight stage, another round-robin style competition.

Points will be carried over from the pool stages into the Super Eight, which will consist of two pools of four.

The top two teams from each Super Eight pool will move into the semi-finals.

There will also be a Rugby World Nations Cup for the developing nations of world rugby.

Q: What are the main changes in the latest RFU proposal?

A: The number of stadia to be used has been expanded, bringing in Wembley, Murrayfield and the Millennium Stadium as potential venues.

The RFU has also agreed to scale down its second tier tournament, the Rugby World Nations Cup, from 32 to 20 teams in a bid to reduce costs.

And a �20m package has been put in place to compensate unions for any loss of revenue from international and domestic competitions as a result of the World Cup.

Q: Why have new grounds been introduced and what games will they host?

All three of the above grounds have a capacity of between 67,000 and 90,000 and the additional gate receipts would provide further revenue as well as enable more people to watch the bigger games.

Wembley has been allocated one pool match, two games at the Super Eight stage and one semi-final.

Discussions are ongoing concerning both Murrayfield and the Millennium Stadium.

Q: Scotland and Wales had looked set to back France's rival bid for the tournament. Is the RFU trying to win votes by guaranteeing games in both countries?

A: RFU chief executive Francis Baron says not, insisting the purpose of using both Murrayfield and the Millennium Stadium is aimed at spreading the game to a wider audience.

Q: When will the tournament be played?

A: The RFU is keen to host it from June to July, with France preferring an autumn schedule. The final decision rests with the International Rugby Board (IRB).

Q: Britain is renowned for its dire transport links. Could that prove a problem for hosting any event of this magnitude?

A: The RFU believes this is an issue for the British Government, which has already endorsed the Rugby World Cup bid. Negotiations are already taking place between the two sides in a bid to avoid any transport mishaps.

Q: How will the RFU's �20m compensation package work and who will benefit?

The compensation will be spread among all the major unions as the IRB deems appropriate.
