Lewis Hamilton today criticised the FIA's controversial changes to Formula One.

The McLaren star attacked motor sport's world governing body who announced on Tuesday that the champion will now be the driver with the most race wins instead of the one with the most points.

A voluntary budget cap is to come into force next year as the FIA seek to further slash costs and attract new teams.

Teams will then have a choice between freedom to spend, but forced to adhere to the current technical regulations, or enjoy a freedom of innovation, but within the £30million cap. That could lead to a two-tier Formula One that may confuse fans as some teams next year will be running under one set of rules, and other teams racing via a different system.

Hamilton (right) fears the changes will damage the sport for spectators.

"I think it's a shame what's happening to Formula One," said the reigning champion.

"It's hard to believe these recent decisions will improve things for the trackside spectators and TV viewers, who should always be our No1 priority, but I guess we will have to wait and see.

"Whatever the points system, I know all Formula One drivers will always race our hearts out.

"For the first time in recent years we have the teams, drivers, sponsors and fans all working together for the good of our sport - now we just need the governing bodies to listen to us and help us.

"Formula One is the pinnacle of motorsport and that's what we all love about it. We should all be working together to maintain that."
