Zara Phillips and Mike Tindall

Zara Phillips and Mike Tindall

Zara Phillips fell off her horse on her first engagement since having a miscarriage.

The 35-year-old former Olympian and her husband Mike, 38, attended the Pacific Fair Magic Millions Polo in Queensland, Australia over the weekend - the royal couple's first public appearance since they tragically announced they'd lost their baby.

According to the Daily Mirror newspaper, a spokesperson said Zara was "keen and ready to play" a game of polo.

Zara and Mike were expecting their second child in the late spring, but a spokeswoman for the couple confirmed the sad news in December.

She said: "Very sadly, Zara and Mike Tindall have lost their baby. At this difficult time, we ask that everyone respects their privacy."

The spokeswoman declined to give any further details about the couple's loss of their baby, while Buckingham Palace said it would not comment on the private matter.

The couple already have a two-year-old daughter called Mia, and they announced in November that they were expecting a baby, revealing they were "very, very happy".

At the time, Mike wrote on Twitter: "Just a quick one to say thank you for the messages. We are very very happy about the little one on its way. 2017 is already starting well!! (sic)"

Zara and Mike - a member of England's World Cup-winning rugby team in 2003 - have been married for five years.

Zara, who is the daughter of Princess Anne, does not hold a royal title, but she is among the most recognisable members of the family and even won a silver medal in equestrianism at the London 2012 Olympics.
