BBC Formula 1 presenter Jake Humphrey caused gridlock in a Norwich bookshop this morning as he signed copies of his autobiography.

A steady queue of more than 60 fans of all ages snaked around the inside of Waterstone's in Castle Street as the TV star launched The Inside Track: Paddocks, Pit Stops and Tales of Life in the Fast Lane.

The 34-year-old, a former Framingham Earl and Hewett School pupil, said he was 'blown away' by the reaction of fans, who bought up every copy of the book in Waterstone's for him to sign – before moving on to buy Jarrold's stock too.

'I was a bit nervous before the signing, and a bit worried that no one would turn up,' he said. 'It's like the feeling you have when you hold a birthday party, before everyone arrives.

'But it was amazing to turn up and see the queue.'

He admitted to feeling 'protective' over the book, which he has written himself without the assistance of a ghostwriter. It tells the inside story of Mr Humphrey's time hosting the BBC's Formula 1 coverage, jetting off to exotic locations and offering an insight into the sport's biggest characters.

'If I've got my name on the book, I want it to sound like me,' he said. 'It was a daunting thing to take on. After lots of the races earlier this season, everyone would be going out having fun but I would be stuck up in my hotel room writing my book.'

He added: 'I've had an incredible four years covering Formula 1 and this feels like a fitting full stop to it all.'
