Questions over the legality of the floor of the Red Bull are likely to spill over into the next round in Canada after rivals opted not to lodge a protest at the Monaco Grand Prix.

Ahead of the Sunday's race there was speculation that McLaren, Ferrari or Mercedes might protest Red Bull's results as it was rumoured they believed holes towards the rear of the RB8's floor were illegal. In the end there was no protest, but both Ferrari boss Stefano Domenicali and McLaren boss Martin Whitmarsh said that they wanted clarification on the issue before the next race.

Asked when the issue should be clarified by, Whitmarsh simply answered: "Shortly."

Domenicali added: "It's part of the game, it's part of the complexity of the rules, it's part of the process that is in place with the Federation [FIA], that's the only thing I can say. It's not easy to have so many things that have to be considered. I think that we'll have a discussion for the future about different details, but this is part of the game."

Meanwhile, Red Bull boss Christian Horner is confident his team's car is legal.

"We're totally happy that our car fully complies with the regulations and we've obviously consulted with the FIA over it. We've had their opinion in writing confirming our interpretation so it would be disappointing if there was a protest, but we're entirely happy that the car fully complies."
