Fewer people want to become headteachers, according to the National Association of Headteachers, which is blaming stress and a lack of training.

Figures obtained by BBC Wales show that Gwynedd council had to re-advertise 22 headteacher posts in the past five years.

Neil Foden, headteacher at Friars Comprehensive School, Bangor, and a member of the national executive of the National Union of Teachers, explains some of the pressures to Bethan Rhys Roberts on BBC Radio Wales' Good Morning Wales.
