Tributes have been pouring in for Mark Speight, the most revealing from his SMart co-presenter Kirsten O’Brien.

Having worked with the 42-year old on the BBC children’s art show, O’Brien described her friend of 12 years “without doubt the funniest man I’ve ever known.”

“Filming days were a joy as Mark would often have the crew and I doubled up with laughter and I think that showed on screen.

“As well as his fantastic art skills, Mark had a childlike enthusiasm for life which is what made him such a hit with young viewers.

“As a friend, Mark was gifted with making people laugh, he lifted your spirits, and his sense of the ridiculous was a delight.

She added to the Sun: “I’m proud to have had Mark in my life and am devastated at losing him in such a terrible way. All of his friends will miss him deeply.

“Mark could find light in the darkest situations for others. I’m only sorry he couldn’t find it for himself. My thoughts are with his family.”
