The hunt has been on since October to find the owner of the winning ticket, bought in Bexley, who has won an incredible £10,633,323.
National Lottery players are now being urged to check and double-check their tickets to be in with a chance of claiming this life-changing prize.
The ticket was bought on October 4, and the buyer matched all six main numbers.
The winning numbers were 6, 8, 12, 33, 49 and 59.
Anyone who purchased a ticket in the area should check their tickets for the lucky numbers.
The lucky ticketholder has until April 2, 2026, to claim their prize.
Andy Carter, Senior Winners’ Advisor at Allwyn, operator of The National Lottery, said: “This is a massive win for one lucky Londoner, so we urge Lotto players to check their tickets to see if they are our would-be multi-millionaire.
“Were you in and around Bexley in the week leading up to the 4 October draw?
“Maybe it isn’t even a local winner – did you visit the area for the day and play Lotto – did you return home and stash it somewhere safe?
“Think back to where as I want nothing more than to unite the winner with their prize money.
“Imagine this sum of money in your bank account in the run up to Christmas – this is a massive jackpot and I can’t wait to meet the lucky ticket holder.
“Tell your friends, check your pockets, check your tickets as it could be you!”
The £10M jackpot win follows a bumper month of big Lotto and EuroMillions wins.
Two EuroMillions jackpots were won in draws just a week apart.
A single UK ticketholder won £26 million on October 3.
Another person won £25 million on October 10.
The missing £10 million jackpot winner was followed by a £2 million jackpot winner on October 8.
