29d Red From a blow (4) Can I add to the debate - I question beet because of the spelling - if clue had said 'sounds like' or had a question mark then beet could be it - but I prefer LEFT which is both red and a punch
I also question WELT which would have been a better answer if this had been the GK crossword
Thanks for coming back to me. The Telegraph has been using red or reds for 'the' left for many years now, so personally I have no doubt whatsoever. Thanks again.
