Mephisto 2473

12a Aim to be in lead, performing what should be taken out (7). - R L E - D A

I can't think of any word that fits, and wonder if I've got something wrong.

[bathtub]

DELENDA I think. I've sent mine off, and can't remember the intersecting clue.

Thank you, Bathtub. That makes perfect sense. The one I've got wrong is:

5d Stop being worried about support going down sharply (7) S T - E - T O. It's obviously steep-to. All sorted now.
