Enjoyed today's challenge from Imogen. Steady progress before being held up in NW corner.
The article in 1a was new to me, as were the answers at 2 and 4 although both solvable from the wordplay.
Knew the themed characters - early evening viewing just before the news back in the early 70's - helped unlock NW corner.
FOI 11, LOI 16
Thanks Imogen and Brendan
