Here I am on a Monday which means a failure to solve over the weekend. NE corner was the problem and I picked up a few from the thread (thanks everyone) but I have, even after having read the whole thread, no ideas for 6D or 17A.
Sometimes seems odd that the ones I get stuck on are hardly mentioned at all - must say something about my odd brain I guess.
Gently hints appreciated. I'm assuming, and that it's safe to say on Monday, that the 'heart' of Manchester is somewhere in 6D, but I'm tired of looking at this and would just like to see it done, although I could wait for 225.
BTW - someone did post the last part of 4D so should be suitably admonished.
