While the prohibition of body piercings has been in place since 2004 and is now being reinforced by F1's new race director, Niels Wittich, Lewis Hamilton insists on continuing to wear jewellery. Here, let's take a look at Hamilton's take on the issue.
In a show of defiance, Hamilton competed at Sunday's Australian Grand Prix with piercings in both ears and a nose stud. He later said 'These ones on my right ear are welded in so I would have to get it chopped off. They will be staying.'
Hamilton could theoretically be fined or docked points if he breaks the sporting code.
It is understood that the FIA is waiting to see if Hamilton's stance will change over the coming races before determining whether action is required.
