The Royal Zoological Society of Scotland has said that there "may be bad news" over giant panda Tian Tian's pregnancy, and may have suffered a miscarriage.
Scotland Correspondent Debi Edward reports
As you are all probably aware, giant panda Tian Tian is now past her due date and the evidence suggests that this may be bad news. She is still displaying some of the behaviours of a pregnant panda, but the scientific data from the urine analysis of her hormones is becoming more atypical. There is still a chance she will give birth to a live cub as her progesterone levels have not yet returned to base.
