The Queen's granddaughter Zara Phillips has got engaged to her long-term boyfriend Mike Tindall.
Mr Tindall proposed to his partner on Monday night at their Gloucestershire home and the Queen and Duke of Edinburgh are said to be "delighted" by the news, a Palace spokeswoman said.
A Buckingham Palace statement said: "The Princess Royal and Captain Mark Phillips are pleased to announce the engagement of their daughter Zara Phillips to Mr Mike Tindall, son of Mr Phillip and Mrs Linda Tindall."
A spokeswoman added: "The Queen and the Duke of Edinburgh are delighted with the news. They got engaged yesterday evening at the couple's home in Gloucestershire and a date has yet to be set."
The Queen's granddaughter is a professional horserider and one of Britain's top equestrians who is also a former world three-day eventing champion. Like her mother, who was also a member of Britain's equestrian team, Zara was crowned BBC Sports Personality of the Year in 2006 by the British public.
Her husband-to-be, who plays for club side Gloucester, has been capped 66 times by his country and was part of the England team that won the 2003 Rugby World Cup.
