The fourth series was aired during 2010, between 17 April to 5 June; a single episode of this series, intended for airing on 22 May, was pushed back to 23 May, in order to avoid it clashing with live coverage of the UEFA Champions League Final that year. The auditions were once more held across the same five cities as before, though the series also held auditions with Newcastle upon Tyne; the city had been originally planned to hold auditions for the previous series, but these were cancelled before this could happen. Owing to illness, Cowell was unable to attend the Birmingham auditions, which led to Louis Walsh being in brought in as a guest judge for these. The series was won by gymnastic troupe Spelbound, with dancing duo Twist and Pulse coming in second, and drummer Kieran Gaffney placing third.
