Lewis Hamilton F1 champion: Jackie Stewart hails Hamilton's hat-trick
Sir Jackie Stewart says Lewis Hamilton "must be ecstatic" after winning his third World Championship to equal the Scot's British record.
"It's great for Hamilton," said Stewart, who won the last of his three world titles in 1973. "I had the record for a long time so I am happy to share it."
Hamilton secured his third world title with three races to spare after a thrilling win in the US Grand Prix in Texas.
