The £184m EuroMillions jackpot winners are going to go public on Thursday.
It has now been revealed they are a couple from Gloucestershire.
Last week their lives changed forever when the pair became the biggest-ever UK National Lottery winners when they scooped the prize.
For the past week, their identities have remained a mystery after they won £184,262,899.10.
Now the couple will reveal some of their plans on how to spend their win, lottery operator Camelot said.
Also, the pair will tell the world how their win will transform the lives of their whole family.
More details are set to be revealed on Thursday.
Their winning numbers were 3, 25, 27, 28 and 29.
Of the win, Camelot’s Andy Carter, senior winners’ advisor at The National Lottery, said: “This is absolutely incredible news. Last night saw history made with the biggest ever National Lottery prize won by a single UK ticket-holder, and we’re ecstatic that we’ve now received a claim.
“Our focus now is on supporting the ticket-holder through the process and helping them start to enjoy their truly life-changing and record-breaking win.”
This is the second EuroMillions jackpot won in the UK this year.
The £109 million jackpot from the draw on February 4 was claimed a few days later.
But the winner chose not to go public.
The record for biggest UK National Lottery win was previously held by an anonymous ticket-holder who banked £170 million in October 2019.
