Marcus Setchell, 69, who was the Queen’s gynaecologist for two decades, was in charge.
He helped save the lives of the Countess of Wessex and her eldest child Lady Louise Mountbatten-Windsor in 2003.
Sophie was rushed to hospital suffering severe internal pains when she was eight months pregnant.
She was dangerously ill from blood loss and doctors performed an emergency Caesarean.
Lady Louise – the first grandchild of the Queen to be born on the NHS –weighed just 4lb 9oz.
Two years earlier the Countess, 48, was airlifted to hospital after suffering a life-threatening ectopic pregnancy.
