Singapore GP: Haze doesn't faze Jenson Button

Jenson Button tells the BBC's Charlotte Glennie that "hopefully we've got nothing to worry about" after a blanket haze over Singapore.

Forest fires in Indonesia had caused dangerous levels of haze ahead of Sunday's Grand Prix, with authorities advising children and the elderly to stay indoors.

The fires, which happen every year, are a result of slash-and-burn clearances on the islands of Sumatra and Borneo.
