Mrcroft, I hope you didn't really put the puzzle in the bin! It was hard this week, but I feel it was worth the effort.
I've no longer got my copy, but if you post the clues, I'm sure we (the IQ solvers) will be only too happy to help. The clashes become more obvious once you've got a couple. One example is - ...there's an answer that ends 'Al' clashing with an answer that begins 'Drin' - just put the two together.
