A single winner could buy some property on Billionaire’s Row in north London (where houses have gone for around £75m) or perhaps invest in a superyacht. If a UK ticket holder scoops the entire jackpot, they would instantly become the UK’s biggest winner, knocking Gloucestershire couple Joe and Jess Thwaite out of the top spot just two months after they scooped the record £184 million. The EuroMillions lottery game is played in Ireland, Austria, Belgium, France, Luxembourg, Portugal, Spain, Switzerland and the United Kingdom. The jackpot will be capped once it reaches €230m (around £197m) and it is estimated that it could be reached in Friday’s draw. When the jackpot reaches its cap, players who match five base numbers and a Lucky Star can expect a bigger prize because any money that would have gone towards boosting the jackpot is shared among the winners in the next prize tier.
