20th April 1989 - 20th January 1994
Born: February 1965
Presented with Mark Curry, Caron Keating, Yvette Fielding, Diane-Louise Jordan, Anthea Turner and Tim Vincent.
Born John Leslie Stott, John was headed for a career in music technology until a television producer told him he would look good on screen.
After sending a demo tape to every TV station, and dropping the Stott, John was hired to present Yorkshire TV's The Music Box. The show ended in 1987 and so John moved to London.
On 20th April 1989 John became Blue Peter's first Scottish presenter, and also the tallest at a whopping 6'4" - dwarfing co-presenter Diane-Louise Jordan.
On 21st April 1991, John Leslie became the second Blue Peter presenter to take part in the London marathon. Despite being trained by athlete Steve Cram, John found the run gruelling. He finished in four hours, thirty-six minutes.
There was also no rest for John on his last show - he was set John's Final Challenge which involved him abseiling down Television Centre, then completing a velcro and wheelbarrow obstacle course, followed by trampolining and conducting an orchestra in the studio.
After he left he became This Morning's entertainment correspondent over on ITV. Presenting stints on Scavengers, Entertainment Express and Wheel of Fortune followed.
In 2001 John joined Fern Britton to take over from Richard and Judy as the regular hosts of This Morning.
In 2002 a serious allegation made against him in the press about his private life saw him leave This Morning. In 2003 John was cleared of the one charge brought against him.
