Strictly Come Dancing favourite Colin Jackson's dancing skills still stun his sister, she says.

Bookies may have tipped the star to triumph in tonight's final, but Suzanne Packer – who acts in Casualty – still can't believe his talent.

"It's a shock," she said. "I've always known that he's got good rhythm, but I would never have dreamt that he could retain dance sequences and then perform them as though he was a professional."

"I will certainly be rooting with my whole being for Colin to win."

"I have to say, if it went on performance, strictly, then Colin should win," added the actress. "It's not that Darren hasn't been progressing brilliantly, but if I was to go and be incredibly objective, if I was talking about ability and skill factor, I definitely think Colin is ahead there."
