The Duke of Edinburgh has welcomed two Sumatran tigers to their new home at London Zoo.
The £3.6m state-of-the-art enclosure comes with heated rocks and a swimming pool.
Five-year-old Jae Jae and his four-year-old mate Melati, the new residents, are getting used to the new surroundings - and each other.
