Prime Minister David Cameron defended the government’s contentious move to triple tuition at UK universities and said protesters, not the police, should be blamed for last night’s chaos on Parliament street and nearby areas and for attacking a car transporting Prince Charles and Camilla, the Duchess of Cornwall. The royal couple escaped unhurt. Police said the route had been cleared minutes before the royal couple was due to make their journey. The high-profile incident came late in a day of violent protests that left at least 12 officers and 43 demonstrators hurt. London’s Metropolitan Police issued a statement Friday condemning the protests and alleged vandalism that took place Thursday night, claiming protesters intimidated Christmas shoppers and bystanders.
