LONDON (AFP) - Mrs Zara Tindall, Queen Elizabeth II's eldest granddaughter, has given birth to a baby girl, Buckingham Palace announced on Tuesday (June 19).
Her second child, born on Monday in Stroud, south-west England, weighed 4.17 kilograms.
The as-yet unnamed new arrival is 19th in line to the British throne.
Mrs Tindall, the daughter of the monarch's only daughter Princess Anne, suffered a miscarriage in December 2016.
Mrs Tindall is an equestrian who won the 2006 eventing world championships and a silver medal for Britain at the London 2012 Olympics.
Though she is 17th in line to the throne, the 37-year-old has no title and does not carry out royal duties.
Mr Mike Tindall, 39, is a former England rugby captain who was in the 2003 World Cup-winning squad. The couple married in Edinburgh in 2011.
Their first child, daughter Mia, was born in January 2014.
"Mrs Michael Tindall was safely delivered of a baby girl on June 18, at Stroud Maternity Unit. Mr Tindall was present at the birth," Buckingham Palace said in a statement.
Queen Elizabeth, her husband Prince Philip, Princess Anne, her first husband Mark Phillips, and Mr Tindall's parents "have been been informed and are delighted with the news".
"The baby's name will be confirmed in due course," the palace said.
This baby is Princess Anne's fourth grandchild and the seventh great-grandchild for Queen Elizabeth and Prince Philip, who turned 97 on June 10.
The sixth was Prince Louis of Cambridge, the son of Mrs Tindall's cousin Prince William and his wife Kate, who was born on April 23.
A heavily-pregnant Mrs Tindall was seen looking somewhat bemused by US bishop Michael Curry's theatrical, lengthy sermon at the wedding last month of Prince William's brother Prince Harry and Ms Meghan Markle, now the Duke and Duchess of Sussex.
Those ahead of the new baby in the order of succession are all descended from Queen Elizabeth.
Those immediately below are descended from the monarch's late sister princess Margaret, then from the sovereign's uncles and aunts, followed by the Norwegian royal family.
