The UK's only pandas will come face-to-face later for only the second time.

The male Yang Guang and female Tian Tian have a window of just 36 hours in which to mate, after tests showed Tian Tian had ovulated.

The bears were introduced on Tuesday and, despite being brought together five times throughout the day, failed to mate.
