Johnny Ball has become the first celeb to depart the dance floor in Strictly Come Dancing 2012
Following last week's first live show, this week Sir Bruce Forsyth & Tess Daly declared the battle for the ballroom officially underway, as the lines opened for the viewers to cast their vote for the first time this series.
Johnny Ball and professional partner Iveta Lukosiute, and Richard Arnold and his partner Erin Boag, became the first two couples to face the dance-off.
The fourteen couples each danced a Foxtrot, Jive, Cha Cha, Viennese Waltz or Salsa in a bid to impress the viewers at home, as well as judges Len Goodman, Darcey Bussell, Bruno Tonioli & Craig Revel Horwood - in the studio.
The judges' scores were combined with their scores from last week, and then these overall scores were amalgamated with the results of the viewers' votes to decide the lowest scoring two couples facing the dance off.
Both couples then performed their routines again; Richard and Erin did their Cha Cha to Love Shack by The B52s and Johnny and Iveta performed their Foxtrot to Everything by Michael Bublé in a bid to impress the judges and remain in the competition.
After both couples had danced a second time the judges delivered their verdicts:
Craig chose to save Richard saying: "I would like to save, based on content alone, Richard and Erin."
Darcey chose to save Richard saying: "For me, it is about the dance content between the two dances, and who gave me the most confidence in them (as a couple), and for me that is Richard and Erin."
Bruno chose to save Richard saying: "For both couples it wasn't as good the second time round. I do agree for others, and again, for content alone, for that reason I would go for Richard and Erin."
With three unanimous votes to save Richard it meant that Johnny Ball bowed out of the competition.
Reflecting back on the results of tonight's show, Johnny stated: "I think for my age I did quite, quite well. I'm so disappointed I'm leaving, I really, really am."
Sunday's Results show featured a performance from The Scissor Sisters, singing "Let's have a Kiki".
