Hamilton says his piercings are no problem for the British GP

Seven times world champion Lewis Hamilton has dismissed fears he could fall foul of Formula One's governing body at his home British Grand Prix over a ban on drivers racing with body piercings.

The Mercedes driver, who has multiple piercings, was engaged in a standoff with the governing FIA in May but was given an exemption until Silverstone for items requiring special intervention for removal.

That exemption has expired, with some media reports suggesting Hamilton might not be allowed to start Sunday's race, but the driver rejected that scenario when asked at the circuit on Thursday.

"It's kind of crazy to think that with everything that's going on in the world that is the focus of people," said the sport's most successful driver of all time, his nose and ear piercings in place.

"We've got so much bigger fish to fry. I'm vegan so I don't fry fish, but you know," the eight times British Grand Prix winner added with a laugh.

"We've really got to start focusing on other more important areas.

"I will be racing this weekend. I will be working with the FIA. I would say the matter is not particularly massively important. I will work with (FIA president) Mohammed (Ben Sulayem) and his team so we can progress forwards."

The ban on jewellery, as well as the wearing of non-compliant under garments, has long been in the rules but rarely enforced until the FIA clamped down this season.

It says items beneath the mandatory flameproof clothing could increase the risk of burn injuries and has highlighted the risk of critical delays or complications if medical imaging is required following an accident.

Mercedes team boss Toto Wolff told Reuters the conversation was ongoing with the FIA.

"This has been such a long discussed topic and they've come to a consensus," said the Austrian.

"There won't be an issue."
