He tries to appear "statesmanlike," when to me when he speaks, he reminds me of Mr Hodges, the air raid warden in Dad's Army.
I'm sure he's marked other dancers in previous series; "bearing in mind their past performance" when on an occasion they hadn't done well.
The dance off itself is a nonsense. They've already been marked once. So just take the scores the judges have already given them. As Len has the casting vote, it makes the dance off even more of a nonsense.
Maybe next year; "The best of three?"
(I hope Jay hunt isn't reading this).
What I love about this programme is the inconsistencies.
