I am now reading this article, and I met a paragraph saying,
Even backbench Conservative MPs looking for a crumb of comfort, or at least a ladder to climb down, were disappointed. “Having met the prime minister earlier today, I was unconvinced that he had a plan to reach a deal on Brexit,” David Gauke tweeted on Tuesday before voting in favor of legislation stopping a no-deal Brexit. If an agreement really was in the offing, Johnson’s own brother Jo, who resigned Thursday citing the tension between family loyalty and national interest, might well have stuck around.
Merriam Unabridged definitions,
transitive verb 1 : to take off : doff 2 slang : kill, murder
intransitive verb 1 of a ship : to move away from shore : start out to sea 2 a : to go away : depart — used chiefly as an imperative b : to get or be off — used chiefly as an imperative
Definition of off (Entry 4 of 6)
: to go away : DEPART —used chiefly as an imperative Off, or I'll shoot!
So it seems to me none seems appropriate.
Thank you for your support.
