Neil Trotter of Coulsdon, south London, has been revealed Euromillions jackpot winner who scooped a £107.9m prize.
The 41-year-old car mechanic and hot rod racer, who runs a repair garage in Mitcham called Chameleon Coachworks, became the National Lottery's fourth biggest winner on Friday night .
Mr Trotter was so confident he would win a prize he had told staff at his father's office last Friday lunchtime that "this time tomorrow" he would be a multi-millionaire.

He learnt that he was the single ticket-holder to scoop the massive jackpot on Friday evening at around 10.30pm.
He said: "I've always thought I'd win big and I'd had a good feeling all week.
"On Friday evening we were sitting at home when I checked the time and thought the draw must have taken place by now.
"I took out my ticket to check the winning numbers and amazingly one by one they matched. I told Nicky, my partner, 'I've done it, I've won the lottery'. But she told me to shut up and to stop being an idiot.
"Apparently I turned white as a sheet and couldn't sit still, I kept walking round the house - I didn't know what to do with myself. I got her to check the numbers with me and she started screaming!
"Next we called my dad but he said I was being an idiot too and that I should stop drinking. But I hadn't had a drop. Even when we jumped in the car and drove round, it took him a while to realise we were serious. My dad's not often lost for words but he was on Friday night."
Neil and Nicky Ottaway, 33, his partner of eight years, finally headed for bed around 3am but had a restless night before calling Camelot first thing.
