To mark the recent National Pothole Day, the BBC Radio 4 show - You & Yours - decided to focus upon the emotive issue of potholes.   As part of that feature, they chose to focus upon the newly-introduced PotholePro machine from British construction equipment giant, JCB.

To provide some industry credibility to the show, You & Yours went in search of an expert guest.   When they couldn't find one of those, they called Diggers and Dozers instead.
