Cymdeithas yr Iaith Gymraeg marks 50 years

A Welsh language campaign group has been celebrating its 50th birthday.

Vaughan Roderick of BBC Radio Wales spoke to two men devoted to the future of Welsh - the Conservative MP Guto Bebb and the writer and founding member of Cymdeithas, Gareth Miles.

Mr Miles began by recalling how it all started with a minor traffic offence.
