I've found all the clued answers and have all the shaded letters (though not sure of the anagram yet). However I'm totally stuck on the eleven letter central unclued answer. It doesn't seem to make any sense! Any tips greatly appreciated.

What links London and Leeds...and what acronym means the same as the unclued across the bottom? Then take 10 spaces (not 11) and find something else with the same acronym. Then have a look at http://en.wikipedia.org/wiki/M1.

Then you'll be in the position as me! I can't find a suitable 11 letter anagram for the final thing in common using the letters from the green squares. Then there's a 4 letter anagram for what fills the spare space along the middle line.

The eleven letter anagram is a type of weapon used by the US army... I'm back!

The preamble is misleading. The shaded letters provide an anagram of the fourth item, plus an anagram of the entry in the middle cell. Not as stated, that the fourth item is an anagram of the shaded squares plus the middle cell. I don't find the middle cell entry all that terribly 'appropriate' either.

Thanks Haggis58, I'm back here!

[Indy-trier]

Thanks people - especially Haggis 58. As soon as you refocused me on "I'm back" everything fell into place - even the middle cell! Nice one.

All this has me confused. Can someone tell me what the middle one is.

What does it mean "complete the grid appropriately"?

BradleyGas - If you have the other two unclued items in the grid (and there are plenty hints in this thread), you should have no problem filling in the blanks in CRA-N-E-ULA. The shaded letters provide an anagram of the fourth item, plus an anagram of the name of the entry in the middle cell. Even though the latter anagram allows 5 possibilities, only one has any relevance.
