… again.
There is a central issue in this crossword.
Solving was almost a clean sweep.
I attempted but failed to cold solve the two down clues in the leftmost column: 1 and 19, but then got GHOUL at 9 to make a start and my pen hardly left the page while linked clues were solved all over the grid till there was only the one left. 23 MERRY needed a different way of thinking, it fell soon enough after a break

Just saw a woman come out of a border shop.
Her bag of shopping split & there was milk & onions & bread all over the place.
A man walking by stopped.
They looked at the mess oozing off down the road & then at each other.
“Bit of a Brexit, there”, says he.
“Aye, ‘tis”, says she.

Here he is at the negotiations

How it works

The Eye’s proprietor (as Cyclops well knows) is Strobes’ employer, Lord Gnome, who would not have been best pleased by the wording of the clue for 26ac.
John, you are correct.
I see now that I forgot to complete whatever it was I was going to say about that clue 26A.
I solved it as “Strobes” readily enough but when I came to write “The Eye’s Proprietor is …” I was struck by the Curse of Gnome and all thought of completing the sentence vanished. And is still nowhere to be found (such is the power of the curse).
As you say The Eye runs under the beneficent auspices of Lord Gnome, and E.Strobes is merely his humble and grateful lackey. This Wiki page explains fully https://en.wikipedia.org/wiki/Recurring_in-jokes_in_Private_Eye#Stereotypical_and_exaggerated_personifications_of_people_and_organisations
I got stuck completely on ‘merry’ and failed to complete for the first time in ages. However, I thoroughly enjoyed the solve while on holiday. (might the holiday have messed with my capabilities, I wonder?). The bottom left corner was empty till near the end. I think I enjoyed ‘protect’ most of all.
