Lewis Hamilton has condemned reports of racist abuse towards attendees at the Austrian Grand Prix, leading a host of other leading Formula One figures in affirming such behaviour has no place.

A packed crowd was in attendance at the Red Bull Ring in Spielberg, with over 300,000 fans on site over the three days, which culminated in Charles Leclerc's season-reviving victory ahead of world champion Max Verstappen.

Hamilton drove to a surprise third to round out the podium after Ferrari's Carlos Sainz suffered an engine fire, further underscoring Mercedes' improvements after a strong finish at the British Grand Prix a week prior.

But the Briton, who has been the target of frequent racist remarks and attacks throughout his career, has called out allegations that some attendees were verbally abused as a product of "ignorance".

The 37-year-old had described reports of racist and homophobic abuse as "disgusting" earlier in the race weekend and doubled down in his subsequent statements.

"It just highlights that it's still an issue all over," the seven-time world champion said.

"It comes down to education and, of course, ignorance. People should come, should feel safe, should feel included and should be able to follow whoever it is you want to follow.

"[It] shouldn't matter [about] your gender, your sexuality, the colour of your skin. It should just be everyone here to have a good time."

Verstappen – whose partner's father, former Brazilian driver Nelson Piquet, was involved in a racism storm concerning remarks about Hamilton last month – also condemned the claimed abuse.

"I read a few things, a few shocking things, so that's clearly not okay," the Dutchman added.

Meanwhile, Leclerc called for bans to be issued to those responsible, adding: "If we manage to find these people, we need to take hard action. They shouldn't be allowed to be anywhere close to our sport."

Red Bull team principal Christian Horner further added: "This is completely unacceptable, and we hope that security and the authorities deal with this swiftly as there is no place for it in racing or society."
