Incidentally, does anyone know how the accessible version works: There's a line number followed by letters such as BDFHJ... etc and then clue 'numbers' like 10A, 13M and so on?
The blank letters tell you where the blocked cells are in the grid. So in line one for example the only blocked cell is 9 and that corresponds to the letter I.
Then 5a starts at the position of J so is written as 5J.
I’m not entirely sure who this is intended for though…
Thanks Jono! I've been thinking for the last hour that there might be a way to make the italicised 'entirely' work - something to do with a homophone, stressing the last syllable, then an exclamation - so it's a bit of a disappointment to learn it's just the Grauniad being the Grauniad.
