'I had to tell children on Newsround': Mark Speight's SMart co-star Kirsten O'Brien reflects on the 'horrendous' experience and 'weird' pressure of reporting his suicide on kids' TV
The SMart frontwoman, 39, spoke on the The Hot Mess Mums Club podcast about her late colleague and friend's heartbreaking suicide in 2008
Mark died at 42, when he was found hanged in Paddington Station in April 2008, after the death of his fiancée Natasha Collins, who died in January that year
Kirsten presented SMart, from 1999 to 2009 and became close to her co-star leading to the request for her to speak about him on Newsround
