Private Ford Fiesta WRC driver Mads Ostberg will start Rally Finland with a new co-driver after he and Ola Floene have parted ways for "sporting reasons".
Floene moved from co-driving Andreas Mikkelsen to work with Ostberg at the start of last season and will now be replaced by Torstein Eriksen and Patrik Barth – both of whom are contracted to the Ostberg family team Adapta Motorsport.
Team principal Morten Ostberg said: "This is a team decision. We have seen over a period that there have been challenges in the relation between Mads and Ola.
"In the end, we must think about what is best for the team. On [a] high performance level, everything has to run smooth."
Ford Citroen and M-Sport factory driver Ostberg is driving his own 2017-specification Fiesta this season, but has struggled to make the sort of impact he had hoped for, a brace of seventh places are the highlights of the five WRC rounds he has started so far this season.
Floene will continue to with Adapta on a separate element of the programme.
