An English wildlife park has offered a new home for the 'world's saddest' polar bear.

An aquarium in the Grandview shopping centre in Guangzhou, China has attracted controversy since it opened in January.

The aquarium is said to home to a number of animals, including walrus calves, arctic foxes and young beluga whales.

However, activists have heavily criticised the quality of the conditions at Grandview.

Earlier this year, the attraction made international headlines when it was reported that it was home to what was described as the 'world's saddest polar bear', named Pizza.

Footage showed the bear having to "suffer for selfies" while restricted to its enclosure.

Yorkshire Wildlife Park in Doncaster, England has now offered to take Pizza in, an animal rights group has said.

The park hosts a specially created habitat for polar bears, dubbed 'Project Polar'.

Animals Asia’s Animal Welfare Director Dave Neale said: “The good news now for Grandview is that they now have the chance to put their mistake right. Thanks to this incredible offer from Yorkshire Wildlife Park there can be a happy ending and the negative publicity they have suffered can yet be turned into a positive news story. 

“As an organisation that works with animal carers to provide the best possible environment for animals, we have to say that we would be delighted to see Pizza end up at Yorkshire Wildlife Park," he added.

The deal is said to have been offered on the condition the Chinese attraction does not replace Pizza with another polar bear or any similar-sized animal.

No payment has been offered for the bear, although the cost of transport will be discussed if Yorkshire Wildlife Park's offer is accepted.

Animals Asia also says it will work for free "to advise and advocate on behalf of the remaining animals" at Grandview.

More than 575,000 people have signed the organisation's petition calling for the aquarium's closure.
