Oops---apologies!
24a is 'PM's sound is harsh sound'. So ?'blare'
21d ib 'high note on electronic whistle'. If 'pipe' is correct------why?
In anticipation,
Jillums...
Stuck on 15a "assembly to advise on the radio".
Can only think "council" but can't break it down. Want the answer to have "air" in it, but it won't fit. Help please!...
