Feel I must add to this discussion.
I almost always complete and submit my solution of the crossword, and have done for ,well - many years now.
Like sarumite it is just for the enjoyment - I have NEVER won - and if I did it would be a bonus.
I think it was consideratae of Kate Mepham to actually add to this thread to explain the error - indeed, it was pleasing to know she tunes into our links game.
It is very rare that such a mistake occurs - I see no reason for the competition to be withdrawn, but if it is, so be it - it is not that important
