Almost one in three lottery retailers will receive an undercover visit from Camelot test purchasers next year as the operator steps up its campaign against underage sales. From February next year, annual visits from teenagers aged over 16 years that look younger will increase to 10,000 under Camelot's Operation Child test purchasing initiative. Recent figures demonstrate retailers are becoming more savvy, said a spokeswoman. Of 5,018 lottery retailers visited between April 2000 and April 2001, 88% refused to sell tickets to the young actors, compared to 77.5% the previous year. Camelot is launching a nationwide Retailer Vigilance Campaign' at the end of the month to raise awareness of the issue. Point of sale material displayed prominently by all lottery retailers should both educate retailers and act as a deterrent for teenagers, added the spokeswoman. {{NEWS }}
