Anyone who played the National Lottery on Wednesday, February 12 is urged to double check their ticket, as one lucky player who scooped the entire £5 million jackpot has yet to come forward.
The unidentified ticketholder netted £5,051,768 by matching all six main balls on the evening's draw.
Camelot's Andy Carter, senior winners' adviser at the National Lottery, said: "What fantastic news for a very lucky ticket-holder who has secured the entire £5 million Lotto jackpot in tonight's draw.
"Players are urged to double check their tickets for a chance to claim this massive prize."
He added: "Over the last 25 years, National Lottery players have made a huge difference to good causes.
"On average, around £30 million a week is raised for everything from small, local community projects to large, iconic attractions and our famous heritage sites.
"With this fantastic win, the lucky ticket-holder can make a big difference, not only to their life but to that of their friends and family too."
