Princess Anne’s son, Peter Phillips, has officially announced his engagement to girlfriend Harriet Sperling. The couple, who have been dating for a year, have not yet set a date for the wedding but are said to be delighted by the news. Harriet, a NHS paediatric nurse specialist and single mother, has a strong relationship with her soon-to-be royal in-laws and has been seen at public events with Peter. The couple’s families have expressed their joy at the engagement, with both sets of parents being informed jointly of the announcement. Despite living a life outside the public eye, Harriet has high-profile connections and is related to the Duke of Gloucester through her late father.
