England now has the largest polar bear centre in the world outside of Canada, following the arrival of three cubs and their mother at a park in Doncaster.
They join four male polar bears already living at the Yorkshire Wildlife Park, which has been dubbed the polar bear capital of Europe.
The 18-month-olds are triplets, which are rare for polar bears, and are settling into a new enclosure with their mother, Flocke, aged 12.
Interview with: Dr Charlotte Macdonald, animal director at the park.
