Former Mini World Rally Team team manager Campbell Roy has left the squad.
Roy had been at the heart of what was the factory Mini team and his departure will leave a void in the management side of the renamed Prodrive WRC Team. Prodrive stalwart and former Subaru World Rally Team operations director Paul Howarth will take over Roy's role.
A Prodrive source said: "We will miss Campbell, he was one of the hard working guys who made sure everything was done with no corners cut. It's a big loss for us."
Roy joined the team 12 months ago.
Prodrive's Richard Taylor confirmed a reshuffle of staff last week, reflecting the company's loss of manufacturer status, although the team and the ongoing development of the Mini John Cooper Works WRC is still funded by the BMW Group.
Prodrive recently revealed the latest upgrades for the Mini, with more than 100 improvements on the car available (FIA homologation this week pending) from the Rally of Portugal onward.
