Two of Edinburgh Zoo's famous pandas are being sent back to China after failing to breed since they arrived in Scotland over a decade ago.
Male Yang Guang and female Tian Tian, also known as 'Sweetie', have been together in Edinburgh since 2011 - but experts have admitted romantic feelings have failed to blossom between the pair.
Zoo keepers have had to resort to artificial insemination since 2013, reports the Mirror.
