A EuroMillions ticket bought in Britain has scooped the jackpot for the first time, UK lottery operator Camelot says.
The first draw was in February 2004
Camelot said the unknown ticketholder won £16.7m - the biggest prize since the draw was launched in February.
The draw links the UK lottery to its equivalents in France and Spain - where previous winning tickets were bought.
It is the sixth richest prize in UK lottery history.
The £22.6m prize won by Mark Gardiner and Paul Maddison, of East Sussex, in 1995 remains the record
To win the jackpot, players need to match five main numbers from 1 to 50 - and
2 Lucky Star numbers from 1 to 9.
