ITV's Dancing on Ice is allegedly facing an 'uncertain future' after skating legends Jayne Torvill and Christopher Dean announced their retirement.This comes as the show's ratings continue to drop, with only 2.9 million viewers tuning in on January 28, a far cry from the 12 million during its peak. "Dancing on Ice faces an uncertain future.The ratings are low for a big weekend show and without Torvill and Dean putting in their performances this could be the end of the road," an insider revealed to The Mirror.
