Car mechanic and hot rod racer Neil Trotter went public with his win today, accepting the huge cheque at a press conference in his home county Surrey, alongside his partner Nicky Ottaway.
The 41-year-old, from Coulsdon, discovered he was the single ticket-holder to the fourth biggest jackpot in UK lottery history on Friday evening at around 10.30pm.
ITV News Correspondent Rupert Evelyn reports:
He said he wad been so confident he would win a prize that on the day of the EuroMillions draw told staff at his father's office that "this time tomorrow" he would be a multi-millionaire.
"I've always thought I'd win big and I'd had a good feeling all week," he said. "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, had a restless night before calling Camelot first thing on Saturday morning.
Trotter, who runs a repair garage in Mitcham, south London, initially plans to splash the cash on two Range Rovers, at least one house, and a horse.
