A record number of National Lottery players became millionaires in the last year, operator Camelot has revealed.
Some 358 ticket-holders received cheques for £1million or more in 2017, up from 347 in 2016, sharing £796million.
The year's biggest prize was won by an anonymous EuroMillions player, who banked £87million in June, while in the same month another anonymous ticket-holder scooped the year's largest Lotto win of £21.3million.
One lucky player could win an estimated £23.5million prize in Wednesday's Lotto draw after the jackpot hit its cap.

A total of 782 people won £50,000 or more this year and Mr Carter said: 'We have had the joy of meeting each of the 782 big winners and watching them start to enjoy their life-changing win.
