Totally agree Marahari12, this crossword had a lot of duff clues, so many infact that it wasn't a pleasure to do, as is usually the case. 5a seemed to need a space between church and man to work properly and I was anything but staisfied with AIRLINES for 17d. 8d should have been GOL LEAF, not the other way around, oh well.
Yeah I noticed that leaf gold thing and had to google it in the end. I wasted a fair bit of time and eraser trying to get the other answers to fit gold leaf! It is used but I would not have written it in with any confidence if all the other answers around it did not fit.
I started doing these crosswords in the mid 80s and rarely ran into a dodgy clue but now it seems de riguer! Actually back then many of the clues were actuallt classics!
