Palin and Jones: 'We didn't talk about the stammer'
Around one and a half million adults in the UK have a stammer. For some - it is obvious when they speak. For many others, it's something they manage to hide - sometimes from even those closest to them.
Former Welsh international Mark Jones and actor Sir Michael Palin, whose father had a stammer, talk about the speech disorder.
I can't say my name - Stammering in the Spotlight - is on BBC IPlayer.
You can get more information and help about stammering from the charity Stamma.
