Regardless of the content of what Mr Brand had to say, and some of it I thought was very sensible, what stuck out like a sore thumb, apart from his dress sense on such an occasion (!), was the way in which his speech is so liberally sprinkled with glottal stops '?'.
I notice today that Gordon Wells’s phonetic blog devotes a posting to exploring the question of how far we can expect to see the use of the glottal stop extended. Almost infinitely if Mr Brand is anything to go by!
