Walsh furious after Cowell and Cole refuse to back his choice

Louis Walsh stormed out of 'The X Factor' auditions yesterday.

Walsh was infuriated when his fellow judges Simon Cowell and Cheryl Cole failed to put through a male singer he had said "100% yes" to after he auditioned at London's ExCel centre.

After rushing backstage to comfort the unnamed singer, Walsh expressed his disappointment to programme host Dermot O'Leary that the mystery man - described as in his 20s - had not been voted through to the next round of the competition.

However, Walsh then returned to his seat to continue assessing the remaining acts.

A show spokesperson told the Daily Mirror newspaper: "Louis was back in time to judge the next act."

Unlike the other regional auditions, Cowell has not chosen a guest judge to step into Dannii Minogue's place while she is on maternity leave.

Previously, Geri Halliwell and Natalie Imbruglia have helped choose contestants to make it through the next stage but the fourth seat was axed temporarily following the guests' unpopularity with the audience.

However, singer Katy Perry is expected to take a seat on the panel when auditions move to Dublin next week.
