Is David Cameron The Stig?
Everyone has their own theories as to who is behind the most famous white racing helmet on British TV, but very few people know who Top Gear's Stig really is.
Ignoring the ridiculous Michael Schumacher 'reveal' on the show last year, the BBC has always kept the secret identity of their anonymous racing driver very close to their corporate chest.
Now a new personality has thrown his name into the ring – Conservative leader David Cameron.
The wannabe Prime Minister was captured removing the distinctive white helmet on video – but only to record a birthday message for Jeremy Clarkson.
According to The Sun, the controversial Top Gear front man celebrated his 50th birthday this weekend with a lavish party attended by celebrities such as The Who's Roger Daltrey, Jodie Kidd, Jimmy Carr and his fellow hosts James May and Richard Hammond.
So the mystery of The Stig's identity continues, and we promise we don't even know – a Top Gear insider refused to tell us when we asked recently. The secret remains safe.
