This is evidently, a rightpondian expression. Just heard it today in reference to the coalition working in Lybia. Not quite NATO (the Germans and Turks are against it). Not quite EU, possibly pieces of the UN.
“It’s a cat’s breakfast”.
Any notions of origins? I don’t see a cat’s breakfast as particularly messy. Maybe this piece of art dated to 1913 gets at the idea.
This Am. general (ret.) also used the expression “we have lots of things in the kit bag” which is also rightpondian, I think. Maybe he spent some time in the UK.
