F1 News Today: Lewis Hamilton denies speeding charge as Ferrari investigation begins

Lewis Hamilton has contested a five-second penalty issued by the FIA for exceeding the pit lane speed limit by 0.1 km/h during the Monaco Grand Prix, presenting a defence against the ruling. Ferrari has launched an investigation following Charles Leclerc's race retirement (DNF) at Monaco, with Leclerc expressing frustration over brake issues and scrutiny falling on the team's brake supplier. Meanwhile, Christian Horner, sacked as Red Bull team principal last July, is returning to work in a new role outside of F1.
