I knew as the BBC (which has educated me enormously over the years regarding non-political matters) took over all major BBC radio stations simultaneously. Furiously trying to change stations as I drove up over the Blackdown Hills, one could press the buttons for Radio 4 to 1 (my preference) and then onto local BBC radio stations without missing a word of the same broadcast, which went on for hours.
It was akin to the behaviour of totalitarian regimes and reminded me of 'A Clockwork Orange'.Screenshot_2023-05-07-11-06-17-209_com.android.chrome-edit.jpg
