CTC Eroica Britannia tie up.

[firedfromthecircus]

I see that CTC is an official partner to the Eroica Brittania festival.
On what terms has this come about? I ask as it is clear the festival is a 'business' and I wonder about the suitability of a charity tie in.
So is CTC the nominated charity which will get a slice of the profits?
Or what other benefits do the CTC and it's paid members receive?
