Hello all.
The preamble:
A WARNING from Gaston to solvers runs clockwise round the perimeter of the grid, starting at the top left cell, and gives an indication of how the definitions in 12 clues relate to their entries. Four further clues each contain a single superfluous word; these can be sequenced to give the deliverer of the WARNING on which Gaston’s is based. 21 further clues each contain a single misprinted letter which must be corrected before solving; read in clue order the correct letters spell out the venue where the WARNING was delivered. Unchecked letters in the perimeter might give MA’S IN A SIZE FIVE JUMPER. Chambers Dictionary (2016) is recommended. One answer is an abbreviation.
It looked like there would be plenty to sink my teeth into at the end, but nothing too daunting initially. A few extra words and some misprints, all nice standard stuff.
I filled the grid except 32a/d and then took stock of what I’d collected; I hadn’t quite sorted out all of the misprints at this stage, nor had I worked out what was going on with the 12 odd definitions. It was only now that I actually looked at the extra words, and these jumped straight out at me:
WINS TON CHURCH ILL
The corrections I had so far gave PLACE ??EBER STRASBOURG, and it wasn’t too hard to find that Winston Churchill had made a speech at:
PLACE KLÉBER, STRASBOURG
Somehow, however, in my early searches I utterly failed to find the relevant one and so struggled trying to construct the perimeter message. I saw that MESDAMES MESSIEURS fitted for the first part, which was enough to warn me that I might have to dust off the GCSE French. Or use an online translation tool, together with the information that MA’S IN A SIZE FIVE JUMPER … and so I laboriously ground out the warning:
MESDAMES MESSIEURS PRENEZ-GARDE JE VAIS PARLER FRANÇAIS
Or, in English:
LADIES GENTLEMEN BE CAREFUL I WILL SPEAK FRENCH
Naturally, on a subsequent search I found the speech very easily, and can’t work out what went wrong the first time! The Council of Europe website gives the background and includes this address given by Winston Churchill at Place Kléber, Strasbourg on 12 August 1949, complete with video and transcript.
Finally, in 12 clues* I could now see that the answer, while appearing to be an English word is actually a French word for the definition. So corner in French is coin, etc. I should really have got this from how = comment and sand = sable, but it’s easy to be wise after the fact.
Merci beaucoup Gaston!

A very satisfying puzzle. Agreed, CHURCH WINS TON ILL did ‘jump out’ as an entry point, but there was plenty of work to do before and after. Thanks to Gaston, and to Kitty for the neat colour-coded analysis
I didn’t get round to this in time, but am now gutted as it looks amazing! Thanks for the analysis
