I've just had my licence back after adding a new type and have just noticed that under section IX (validity) it says
"A document containing a photo shall be carried for the purposes of identification of the licence holder."
Why not have a photo as part of the licence as in the old days, or would that be too obvious? After all with these things being produced by a computer these days I'm sure they could digitise it and insert it into the document.
Maybe it's just me they don't trust!
