Tory leader David Cameron tries for the third time to do his favourite yo-yo trick

Newly appointed Conservative Party leader David Cameron, faced the biggest test of his leadership credentials today when he admitted that he thinks Westlife are 'really, really cool'.

The blunder comes at a crucial time for Mr Cameron who has spent the majority of his leadership so far appearing on youth based television and radio shows naming favourite bands and favourite characters from Little Britain.

Suspicions that Mr Cameron is being coached on popular persuits of the under 30 demographic were confirmed during a radio interview for Spank FM.

When asked what kind of music he liked Mr Cameron confidently explained that he enjoyed bands such as Radiohead, The Smiths and more recently bands like The Killers.

It now appears that these were the only 3 'favourite' bands agreed in advance by Camerons team, as it was felt that they would generate the most amount of credibility for him across the 18 - 30 demographic.

However Spank FM radio jock Tim Hill was not made aware that there was only meant to be one music based question and seemingly impressed he continued to ask the scriptless Cameron who he thought has had the biggest influence on British music. To this he replied:

"I would definitely say Westlife. Their music is uplifting and inspiring and I am sure I am not alone in saying that. I just think they are really, really cool!".

The Spank FM DJ looked on in amazement as Mr Cameron continued to describe in detail his favourite Westlife songs and how they made him feel.

The embarrassing confession from Mr Cameron could spell a major down turn in the growing popularity of the young leader. Political analyists are predicting that a mistake like this could be extremely damaging for Mr Cameron since voters across all age groups are likely to consider his honest taste in music to be 'really, really uncool'.
