Korean Grand Prix from the pit lane with Ted Kravitz

BBC F1 pit-lane reporter Ted Kravitz with the behind-the-scenes gossip from the Korean Grand Prix, where Sebastian Vettel's victory helped Red Bull wrap up a second consecutive constructors' championship.

Kravitz asks Red Bull team principal Christian Horner about Mark Webber's comments about the timing of his second pit stop, as well as becoming the top team two years running.

Vettel jumped Hamilton on the first lap to take the lead and was unchallenged on his way to a 10th win of the season.
