After the death of Richard Whiteley, the show took a four-month hiatus, returning on 31 October 2005 with Mr Lynam as the new presenter. He was a popular choice with fans, but the commute from Countdown's Leeds home to his own in West Sussex proved too much, and he left at the end of Series 55, to be replaced by Des O'Connor.
Before joining Countdown, Mr Lynam started as a radio presenter, then became the presenter of Match of the Day and Grandstand on the BBC, and later defected to ITV when they bought the rights to show the Premiership. He spent just one year as the host of Countdown, and most recently appeared on adverts advertising Setanta Sports, a now defunct sport channel that used to show Premiership matches.
Mr Lynam has written an autobiography, titled I Should Have Been At Work. It was published shortly after he took over as host of Countdown.
