In the London TMA
And Manchester, and come December, Scottish FIR

All TCAS II RAs are broadcast downlinked (BDS 3,0) by all Mode S capable ground radars while the RA is active. This is an ICAO Annex 10 requirement for the radar system.

At this point in time I believe that Luxembourg is the only European country displaying TCAS RA information to controllers, although many ANSPs are considering it - but is difficult regarding agreement on what benefit it would give a controller knowing an RA is going on against the level of nuisance alerts. And anyway, if its a genuine TCAS RA due to a proximity situation, it is mostly a bit late for the controller to get involved anyway!
