Wasn't it the FIM that set out race nights after BSPA, DMU & SVEMO complained about Poland threatening to run 5 days & banning riders from competing in other leagues??  There isn't officially 'Fixed' days as such, just 'Priority' days to individual associations. Monday - UK Tuesday - Sweden  Wednesday - Denmark  Thursday - UK / Sweden Friday - SGP / Poland Saturday - SGP / Poland  Sunday - Poland Every league can run 7 days if they wanted to, they'd just not be allowed to demand rider availability on an 'off' night. It's why some of the conversations on here have been funny when some say "have one big league and ride any day we want." Rider availability would be disastrous with R/R & guests all over the place. It's probably the biggest reason why British Speedway are desperate to save the top tier league.  Going to 1 league would finish the sport in this country forever, they'd be no coming back from an absolute 💩 storm that would create for our clubs. 

Not really. Riders contracts can be terminated without notice or compensation. The power is very much with the promoters. 

Where is the source of this concept coming from.  Unless I am mistaken, The 2026 GP series will run pretty much in line with 2025 concept.  Or put another way, your post is without foundation and is in fact utter garbage!

If signs in Sweden he won't be allowed to ride in UK as present polish stand is riders can only ride in 2 other leagues.

Are all these returning GP riders going to ride for a lot less money, because if they don't we cant afford them

I would scrap all of the GPs. I am not sure that British Speedway has benefitted too much from having them. The old World Final was a much better way of deciding the World Champion than the GPs. However, we have what we have and I suppose we will have to put up with it.
