To my irritation I can't lay my hands on the info right now, but I do remember it depended on the station being broadcast, Virgin having wider bandwidth than the predominantly voice content BBC stations.

I remember reading an article which was in an old edition of Wireless World from the mid 1930s. It showed the frequency response of a signal sent by land line from London to Droitwich radiated and picked up by the BBC in London. The graph showed that the frequency response went up to 8kHz, So It would appear that in the 1930s the transmitted bandwidth went up to 16kHz. The article also went on to report on the poor stability of overseas broadcasters to maintain correct broadcasting frequencies.
