Ecclestone believes Hamilton will shrug off the racist abuse

And he said an anti-racism campaign launched by governing body the FIA was "not necessary".

"All it does is give attention to people who want attention," he said.

"I don't think they're fans, and I don't think they were supporting [Fernando] Alonso in particular. They just like to abuse people."

Ecclestone described the abuse, in which Hamilton was taunted at a test session at the Circuit de Catalunya near Barcelona by spectators with blacked-up faces and wearing wigs, as "a one-off, nothing to worry about".

He did add, however, that the FIA would have to consider sanctions against the circuit if there was another similar incident.

Hamilton was taunted by fans with blacked-up faces

Hamilton is a target for Spanish fans because of his rivalry with former McLaren team-mate Fernando Alonso, who as Spain's first F1 world champion is an icon in the country.

Ecclestone, who was talking to BBC 5 Live's Sportsweek programme, said he was confident the controversy would not derail Hamilton's preparations for the start of the season next month.

"I don't think he would be affected by it. I think he is strong enough to know it is all nonsense," Ecclestone said.

But Ecclestone did admit the 23-year-old might find his second season in F1 more difficult than his first, when he caused a sensation by coming close to winning the title.

"He was under no pressure at all last year, but this year he is going to be under pressure, and that's the problem," Ecclestone said.

"But I think he is up to it. I think he will cope. It won't faze him. He knows what he can do and what he can't do."
