Ostafinski wrote on Sportowefakty today that BSI insist on having the GP in Prague on the original date. Not sure what's true about this, but it looks very unlikely. Czech federation also says it's impossible.
FIM Europe cancelled their congress in Prague (beginning of July)... so that says already something.
Teterow isn’t going ahead in May for sure. But for some reason there is still no official announcement by BSI / FIM.
I think they are waiting until they have a replacement date. Teterow club said something about September or even October.
