National Lottery players are being asked to double-check their tickets as one worth £12m has yet to be claimed.

The Lotto Jackpot ticket, bought for the draw on 6 June in Rhondda Cynon Taf, matched all six main numbers - 08, 10, 26, 30, 35 and 42.

The ticket-holder of the life-changing sum has until 3 December to claim the prize.

Andy Carter, senior winners advisor at The National Lottery operator Allwyn, said this was an "incredible win for one lucky Lotto ticketholder".

There have been many lucky Welsh winners of the National Lottery throughout the years.

Former Asda worker Sandra Fosbrooke and her factory machinist partner Ken Henry, from Llanelli, Carmarthenshire, celebrated a £12.8 million win back in 2005, using their winnings to travel the world and buy houses, cars and holidays for close relatives.

Les Scadding and his wife Samantha Peachey-Scadding, from Caerleon, Newport, won the £45.5m jackpot in 2009. He was out of work and £68 overdrawn on his bank account on the day he bought the ticket

A family in Monmouth also won the EuroMillions £61m jackpot in 2016, after mum Sonia Davies felt lucky and rang her daughter to buy tickets after she had life-saving cancer surgery.

This year, Tata Steel workers in Port Talbot celebrated winning a £1m lottery jackpot back in February.

The 15 winners, who used to work 14-hour days together in the finance team, planned to use their £66,666 share on paying off mortgages, holidays, house renovations and new cars.

The biggest prize won by an anonymous UK player is £195m in 2022, according to EuroMillions.

Carter said: "Think back to if this could be you, as we want nothing more than to unite the winner with their prize money.

"Imagine this sum of money in your bank account and how it could change not only your life but that of your friends, family and charities or good causes close to your heart – this is a massive win and we can't wait to unite the lucky ticket-holder with their Lotto Jackpot prize."

Winners of prizes have 180 days to make a claim, with any unclaimed funds put towards National Lottery-funded projects.
