If the winner had come forward to claim the prize straight away, they would have instantly joined the likes of top footballers Phil Neville and Robbie Keane, who are both said to be worth around £7 million. The winner would also have been able to earn daily interest of £1,063.
As the 180 day deadline approached, a National Lottery spokesperson appealed for people to look everywhere if they thought they might have bought a EuroMillions ticket in Devon for the 28 September draw, and to check any old tickets they could find in coat pockets, wallets and down the back of sofas.
Unfortunately, the deadline lapsed without anybody coming forward to claim the prize, so the EuroMillions win of £6,989,367, plus all of the interest earned from it, has now been added to the fund for Good Causes.
EuroMillions players who want to avoid missing out on a fortune are advised to keep their tickets in a safe place, to check them as soon as they can after the draw and to make any claim immediately.
