Zara Phillips and Mike Tindall have revealed the name of their newborn baby daughter for the first time.
The Queen’s granddaughter and the England rugby ace had their first child at an NHS-run Gloucestershire Royal Hospital last week.
The baby weighed 7lbs 12oz, and Phillips returned home with the child just three hours after the birth.
Rather than waiting for Buckingham Palace to do the honours, Tindall chose to tell his Twitter followers the name they had selected for her first.
Taking to the social networking site, he posted:
For everyone who has asked what our daughters name, it’s Mia Grace Tindall— mike tindall (@miketindall13) January 23, 2014
Mia Grace Tindall is the 16th in line to throne. She is the fourth great-grandchild of the Queen and Duke of Edinburgh and Princess Anne’s third grandchild.
Buckingham Palace first announced Phillips' pregnancy in July 2013, shortly before the arrival of the Duke and Duchess of Cambridge's baby, Prince George.
The couple met during England's Rugby World Cup-winning campaign in Australia in 2003.
They wed in July 2011 in Edinburgh's Canongate Kirk in a private ceremony attended by all the senior members of the Royal Family, three months after Phillips' cousin Prince William married Kate Middleton.
Phillips won individual gold in three-day eventing at the World Equestrian Games in Germany in 2006. She also won silver in the team three-day eventing event in the Olympics in 2012.
David Cameron's official spokesman described the announcement at the time as “quite terrific news”, telling reporters: “The Prime Minister will send his very, very best wishes to the happy couple.”
The pair are already aunt and uncle to two nieces, Savannah and Isla - the daughters of Phillips' brother Peter and his wife Autumn.
