The Euromillions lottery jackpot in tonight's draw will be £122 million, organiser Camelot has said.
A single ticket winner would become the UK's third biggest National Lottery jackpot winner to date with a fortune twice that of X Factor judge and Take That star Gary Barlow's £60 million, the organisation said.
A Lottery spokesman said a winner would become the joint-649th richest person in the country, adding: "This jackpot is now up to a point which can mean fast cars and private jets."
The largest Euromillions jackpot to date is the £161 million won by Colin and Chris Weir of Largs in North Ayrshire in Scotland in 2011, followed by Gillian and Adrian Bayford, from Haverhill in Suffolk, who won more than £148 million last August.
Last month an anonymous British player won £81 million on Euromillions.
