The winner has just two weeks to claim their prize, after which their ticket will no longer be valid.
A National Lottery spokesman told VRT News that such a large sum remaining unclaimed is quiet exceptional as “such large sums are always claimed”.
It has happened just once in the past that a big win remained unclaimed. This was the 1 million euro jack pot won at the 31 December 2008 draw.
The National Lottery has placed advertisements (see below) in a national newspapers in an effort to find the winner.
