Serbia’s state lottery is facing an investigation after one of the winning numbers appeared on television before being drawn. During a live broadcast on Tuesday evening the fourth ball drawn was 27, but the programme mistakenly declared the number chosen had been 21. The station immediately realised its error and added a number 27 graphic to the winning numbers; but the next ball chosen was indeed 21. Lottery chief Aleksandar Vulovic said an employee mistakenly typed 21 instead of 27 but he has resigned out of “moral obligation” so an investigation can take place.
