Team UK's rivals are being told to "put up or shut up" ahead of the next phase of the America's Cup Challenger Selection Series on Auckland's Waitemata Harbour. After an eventful round robin series, Team UK secured a spot in the finals and now has to wait to see if a repaired American Magic or a hurting Luna Rossa come through the semi-finals on top. Team UK's skipper Sir Ben Ainslie wants his opponents to concentrate on their own boat development and stop paying so much attention to what his team is doing. Felicity Reid reports.
