Mark Webber has lashed out at those who believe his Monaco GP victory was achieved in an illegal RB8, saying it "pi**es" him off.
Webber became the sixth different driver to win a grand prix this season when he took the chequered flag around the streets of Monte Carlo.
However, Red Bull faced an anxious wait as there were rumours that rivals would protest the result as they felt Red Bull's RB8 did not conform to the F1 regulations.
The debate was over a hole situated in the floor of the car, however, at the time no protest came although the FIA was asked to clarify the rule.
That verdict was handed down last Saturday with motorsport's governing body ruling that the hole was not permitted and would have to be removed. However, given that no one protested the previous race results, Red Bull and their drivers would retain all their points.
Webber was asked about it during Thursday's press conference ahead of the Canadian GP and made his thoughts very clear.
"In relation to [the allegation of winning with an illegal car], I've been called lots of things, and I'm happy to take a lot of criticism for my driving and lots stuff, but I won't take criticism in that respect," he said.
"It pi**es me off, to be honest, because the car has passed every single technical check and all of the teams that were against the car in Monaco did not make a protest.
"The rule now is different. We had a car that was legal for the first part of the season and now that the rule has been changed we will start again."
The Aussie also downplayed the impact of removing the hole, saying Red Bull intended removing it later in the season.
"I wouldn't know if the floor is changed or unchanged. So we're very optimistic that the change won't make difference at all.
"You won't believe us, but we had some changes for Valencia which included no hole irrespective of the rule change."
