17 Across. Tidy old finance chancellor, in short - get shot! (5) do-ce
Am considering 'douce' and 'dolce' - but can't settle on which. As this is the last answer I've to get, I'd welcome other people's thoughts. Thanks.
The wordplay suggests DO (tidy) + Old + C.E., and 'dooce' means to get fired from one's job (get shot?), although I can only confirm that 'dooce' is a newish bit of internet slang.
