In a move which is certain to lead to further arguments with the manufacturers, the World Motor Sport Council has agreed a ten-year freeze on engine development.

A press release issued following a meeting of the World Motor Sport Council in Paris read: "There will be a total freeze on engine development for a period of 10 years, starting from 2008. A change can be made after five years but only with the unanimous agreement of all stakeholders and following a further two-year notice period. Total freeze means that there will be no exceptions for development of certain parts of the engine, as is the case under the current regulations."

The announcement comes days after the manufacturers submitted their own proposals for the period 2010 - 2013 which they claimed would reduce costs and also be more environmentally friendly, two causes close to FIA President Max Mosley's heart. However, the proposals were firmly rejected by the FIA.

The current freeze was introduced this season, and was expected to remain only until a major overhaul of the engine regulations could be carried out, it was never envisaged that the freeze might last ten years.

Such a technological freeze can only compromise Formula One's supposed reputation as the pinnacle of motorsport, a concern that the manufacturers - and fans - have previously expressed.
