53 across, German resistance group opposed to Nazi regime. I have the answer but don't know if they want the English or German name as both fit. I am inclined to go with the English but what does everyone think?
I agree with 'White Rose'. The German is 'weisse rose' which doesn't quite fit unless you write the special symbol for 'double s' (which would take me ages to find in the character set to include here!!) and I have never seen that or other special character in an English crossword.
