King Charles was left in fits of giggles as he showed off a little-known skill that could save a life. Today, he visited the headquarters of the Royal College of Nursing (RCN) in central London, where he refreshed his first aid skills when he practised resuscitating a dummy patient under the watchful eye of nursing cadets. Charles has been trained in CPR and was happy to join a demonstration when he visited the RCN to celebrate a scheme introducing young people to the healthcare profession.
