One lucky lottery winner could scoop £57.8m on Saturday.

But if no one wins the jackpot in this weekend's rollover Lotto draw, the prize will be split between the winners with the most winning numbers.

Under National Lottery rules, once the Lotto jackpot hits £50m or more, it will roll to another draw a final time — this Saturday's draw.

To win the jackpot, you need to match the six main numbers.

In 2013, Dewsbury man Graham Nield won the £6.6m Lotto jackpot — and immediately proposed to his partner or 10 years.
