The biggest UK EuroMillions jackpot prize was won back in October 2019 by an anonymous ticketholder which was worth £170 million.
However, this Friday the jackpot, which stands at £164 million, could see the UK's second-biggest winner of all time.
If won, it would also mean the lucky ticket holder would become the 14th winner of more than £100 million and the second EuroMillions jackpot won in the UK this year after one banked a whopping £109 million.

Camelot’s Andy Carter said Friday’s top prize could be secured by one ticketholder or shared between multiple winners in participating countries.
Mr Carter said: “Friday’s jackpot is a wonderful amount of money and a winner could do so much good for their loved ones and the local community. I have seen first-hand the difference that winners make transforming people’s lives around them.
“My team and I have our fingers crossed for all UK players and are on standby to support all our big winners as they start their life-changing journey.”
The EuroMillions jackpot is capped when it reaches 230 million euro - or £195,000 - the estimated sum for next Friday (May 13) unless won beforehand.
When the jackpot is at its cap, players matching five main numbers and one lucky star can expect bigger prizes because any money that would have gone into boosting the jackpot will be shared among players in the next prize tier.
Once it reaches the cap and assuming it continues not to be won, the jackpot will stay at the cap for a further four draws until it has to be won in the fifth draw.
In a EuroMillions Must Be Won draw, if no ticket matches all five main numbers and two lucky stars, the entire jackpot prize will roll down into the prize tier where there is at least one winner – likely to be five main numbers and one lucky star.
