Gina Nolan and 11 colleagues in her work syndicate matched six numbers on the National Lottery last Saturday.
The warehouse workers from Biggleswade, Bedfordshire, phoned lottery operator Camelot, which confirmed they were one of three ticketholders who would share the advertised £6.2million Lotto jackpot.

But two days later, Camelot told them there had been a mistake. Blaming ‘human error’, it said it had calculated the jackpot incorrectly – and in fact it would be nearly £1.5million less.
Last night the five men and seven women accused Camelot of misleading them by failing to honour the advertised estimated jackpot. Instead they will receive £124,621 each.
