Wildcard round (18 October)

For the first time (and only time) on the UK version of Pop Idol, there was a Wildcard Round where previously eliminated contestants returned for a second chance at making it through to the live finals. As a result, the final 10 was to become a final twelve. The judges announced which eight contestants would earn a Wildcard place at the end of the 11 October results show, and that after they perform the public would choose one contestant to go through, and the judges would pick another. The eight contestants who contested the Wildcard Round were Jason Brock, Jodie Connor, Glen Harvey, Rebecca Hayes, Susanne Manning, Kieran McDonald, Sam Nixon and Danielle Tedford.

Notes

• The judges selected Sam to move on into the Top 12 of the competition, before the hosts revealed the Top 3 vote getters. Susanne received the most votes, and completed the top 12. It was not made clear whether or not Sam was actually in the top 3, as the hosts stated that it was the top 3 of the remaining 7 contestants. Danielle missed out on the finals by one place for the second time.
• In 2010, Jodie Connor's vocals were featured on the UK number-one single "Good Times" by London grime collective, Roll Deep,^[4] and she later went onto launch a solo career.
