Driver facing test of confidence as team prepares for tire tribunal

Lewis Hamilton is calm about what could happen to Mercedes if it is hauled before a Formula One tribunal to explain its secret tire test, but he is worried about his own form.

"I'm not concerned about it, that's for the team to worry about," the 2008 world champion said of his team's apparent breaking of a ban on in-season testing by putting in 1,000 km with Pirelli in Spain.
