Wish we saw more of this setter. Found this to be excellent with loads of top class clues. Among my favourites were: PROFESSION, IMPERIAL, GLOBE ARTICHOKES & STUART. Nice to see the word BANJAX. Not seen that for some time but kinda like it for some reason. To be picky, the blog should have EEL in 6d.
Thanks to Artexlen and Peedee.
Thanks Jaydee for the correction. Fixed now.
..and thanks to Hovis too. I like it that people take the time to read all the explanations and fix the bits that I have missed.
Enjoyed this one. Liked 10a — good concise clue. BANJAX was new to me. Thanks Artexlen and PeeDee.
Curiously ‘imp’, ‘peri’, & ‘Ariel’ were all fairies hovering in the air around 4 Down, which was charming but more or less irrelevant.
As a Richard Dawkins fan – that man is a god to me – I liked ‘meme’ because it’s a new word whose d.o.b. Is, fascinatingly, set in time.
Good puzzle, thanks to both.
Thanks Artexlen and PeeDee
Am another who likes the crisp clueing and excellent surfaces of this setter. No real holdups, although BANJAX was a new term and had to check the verbal use of NUT. Liked the construction of SEA BREAM and thought that STUART was clever.
Finished in the NE corner with ENERGISE, PROFESSION (good misdirection of the definition) and IMPERIAL the last few in.
