Thanks, Cerasus. That gave me a lead.
I tracked down two sequential puzzles from the Daily Express.
Note the clue in the first:

Carer is left out of sunrise = SUNR(is)E = NURSE No anagrind that I can see. (of ?)
This appears as answer #4 in the solution:

Next clue:
Rudimentary cab is in a smash = [CAB IS]* = BASIC
Apparently the clue/answer is to help by providing some extra letters if one gets stuck.
No letter count so as not to make it too easy.
