A mystery lottery winner has just six days left to claim their life-changing jackpot of £3,681,197.
The winning ticket was bought in the constituency of Inverness, Nairn Badenoch and Strathspey and it matched all six numbers.
But the draw took place on September 23 last year - and the clock is speedily approaching the deadline.
The would-be millionaire only has until 5.30pm on Monday, March 22, to come forward.
A National Lottery spokesperson said: "We are still hopeful that someone will come forward at the last minute to claim the money.
"We're urging everyone to check their old tickets again or look anywhere a missing Lotto ticket could be hiding".
If no one comes forward with the winning ticket before the deadline, the money will go to the National Lottery's Good Causes fund, aimed at helping community projects.
Crucially, the winning numbers on September 23, 2009, were 23, 25, 28, 41, 46 and 47.
