The former Olympic medallist was amongst the bookies favourites to do well, but his performance of the cha-cha with partner Ola Jordan to LMFAO's"Sexy and I Know it", failed to impress.
Bruno Tonioli, who is not known to beat around the bush, had a brutal assessment of the Welshman's performance: “You went to the Neanderthal approach to the Cha Cha and you smashed it to the point of extinction. Dances have to exude a certain character. That was murder."
Craig Revell-Horwood was equally unimpressed, branding the performance too aggressive and scoring it a measly two points.
Iwan and Ola scored just 13 points in total for there performance, leaving them bottom of the leaderboard and heading into the dance-off to face Jamelia and her partner Tristan McManus. Both couples re-performed there renditions of the cha-cha and it was the Loose Women presenter Jamelia who came out on top.
Around the Floor
Jay McGuiness overcame his nerves to score the highest for the week, with a 30 point haul following an exciting rendition of the Waltz with partner Aliona. Helen George and her partner Aljaz performed a strong rendition of the cha-cha to Billy Joel's Uptown Girl, which left Bruno Tonioli impressed, calling Helen “An Uptown Bombshell!".
Bookies favourite Peter Andre picked up where he left off from last week opening show and scored the highest across the two weeks, after receiving 30 points for his performance of the quickstep with Janette.
You'd have thought Jeremy Vine had won the competition, such was his delight at making it through to week two. The BBC Radio 2 presenter had been the favourite to get the axe on week one.
Katie Derham got the biggest audience response of the night, as her version of the Tango with Anton Du Beke received a standing ovation. The radio 3 presenter may be a dark horse for the competition and judge Len Goodman used the performance as an opportunity to joke with Anton, telling him; "This could be the year you realise Strictly goes right up until Christmas."
