Doherty comes to the rescue

Jimmy Doherty's Big Bear Rescue (Sunday, Channel 4, 8pm) was shot over the course of a year, and in last week's opening programme, we followed Jimmy as he embarked on a mission to save two polar bears whose home, Orsa Predator Park in Sweden, was closing down.

Over the past few years, Jimmy’s Farm & Wildlife Park in rural Suffolk has grown from a working farm raising rare pig breeds into an award-winning wildlife reserve, home to a diverse variety of rescued animals, from meerkats and capybaras to zebras and crocodiles.

Jimmy and his team built Europe's largest polar bear reserve on his wildlife park as they awaited the arrival of Ewa and Miki.

And the bears journey from Sweden all seemed to be going well — until disaster struck.
