Zara Phillips has suffered a miscarriage less than a month after announcing her pregnancy. 

The 35-year-old and her rugby player husband, Mike Tindall, 38, are now grieving their loss together, although it is not believed that the British royal is in any medical danger. 

The duo, who married in 2011, already have a three-year-old daughter, Mia.

It seems that she was about four months into her pregnancy with the baby due in late spring.

A spokeswoman for the couple confirmed: "Very sadly, Zara and Mike Tindall have lost their baby. At this difficult time, we ask that everyone respects their privacy."

The Tindalls were due to spend Christmas with the Queen and their extended family in Norfolk.

Zara is, of course, a granddaughter of Queen Elizabeth II and a cousin to princes William and Harry. She is also a equestrian champion and holds an Olympic silver medal from London 2012.
