HILLS ON THE MOVE British bookmakers William Hill today announced that its tax-free internet betting service is to move from the Isle Of Man to Antigua. The Caribbean island is already the centre of the company's offshore operations with a telephone betting service and internet casino based there. There is no betting tax in Antigua and group chairman John Brown cited that as the reason for the move. He said: "In the current competitive climate we have been offering tax-free betting to UK customers and paying the duty ourselves. Clearly we could not carry on doing so indefinitely."
