Only one of the two ticketholders sharing Saturday night's #20m National Lottery jackpot has come forward, organiser Camelot said. One winner came forward yesterday morning after matching all six balls - 24, 20, 47, 8, 43, and 35. The bonus ball was 32. Camelot was not surprised have heard from only one winner so far. ''People come forward over a couple of days. It is a Bank Holiday and a lot of people are away,'' a spokesman said.
