The beautiful bond between father and son lions at Blackpool zoo

Now Father's Day is still a month away but one single dad has been showing off why he deserves a special mention. He's Wallace the lion - at Blackpool zoo who's become inseparable from his cub Khari.

Their special bond grew following the death of Khari's mother and is all the more remarkable because male lions are usually seen as rivals.

Wallace stepped up to the mark and shoulders his new responsibility with pride as Sarah Rogers reports.
