'Happy' Hamilton enjoying Korea

Lewis Hamilton says it is "the first time" he feels practice has gone well for him this season after setting the pace for the Korean Grand Prix.

Hamilton's Mercedes team-mate Nico Rosberg, McLaren's Jenson Button and Lotus' Kimi Raikkonen, who crashed during first practice, also offer their views on the day's action.

Practice was held in crisp sunshine, with meteorologists currently monitoring a tropical storm that is passing through parts of Asia and could affect Sunday's Grand Prix.
