Television personality Nick Knowles has confessed that featuring on a certain TV programme "didn't work out well for me" following his revelation about plans to "disappear" from the small screen. The 63 year old ranks among British television's most popular presenters, with DIY SOS broadcasting on the BBC for a remarkable 27 years and still going strong. Nick recently announced that he intends to step back from professional commitments to support his wife, Katie Dadzie, who needs urgent surgery.
