Cryptic crossword No 234

I really enjoyed this - thanks Meles! My favourites are 15a, 18a, 21a, 22a, 25a, 4d, 6d…

A really good puzzle, Meles - thanks! I particularly liked 6A, 15A (haven’t seen “covering up” used like that before - nice!), 22A, 28A, 4D (well disguised) and 12D (see reply).

A really great puzzle. Surface reading outstanding (better than today’s Everyman). I especially liked some of the simpler clues such as 29a, very elegant. 22a very clever, 4d is lovely and 14d made me laugh. Took a while for the penny to drop with 12d, but worth the wait. The only clue I didn’t like so much was 2d.

Same problems as others below initially took unlimited data as AT but worked it out, the I'm in 10A. Pens in 20D. But otherwise excellent. 14 D and the associated clues was brilliantly done though it perhaps spoiled the surface of 2D. Favourite clue was 25 absolutely lovely .
