Belgium becomes the first European league (I think) to make a decision: rest of the season cancelled, and effectively the most recent standings declared final. So Club Brugge are champions, and Gent go into the CL as runners-up. Relegation still to be decided.

But an important caveat: Belgium has a playoff system after 30 games. They had played 29 of those games, and most of the affected teams had decent gaps. So effectively all they've done is cancel the playoffs. Not sure that solution would hold as easily in, say, Italy or Spain.

Where it may be more significant for everyone else is that they're not annulling, which I suspect is because Uefa has kind of hinted that countries that void may not be able to have CL/EL representation next season if other countries do resolve the season.
