Technical director Geoff Willis has left the Honda team following the news that Shuhei Nakamoto was promoted, autosport.com can reveal.
The underperforming Japanese squad announced on Tuesday a reshuffle of their staff, with Nakamoto being promoted to the role of senior technical director. The news followed the revelation than Willis would be assigned a more factory-based role to focus on the development of the car.
Honda said after yesterday's announcement that "discussions are currently taking place with Geoff Willis, Technical Director, regarding his future role with the team."
However, autosport.com has learned that Willis is no longer working at Honda, although no formal announcement has been made by either side. Neither Honda nor Willis were available for comment.
It remains unclear whether Willis was fired or has decided to quit following the appointment of Nakamoto, but there are strong indications that it was Willis's choice to quit his job.
Willis joined BAR-Honda from Williams in 2002, while Nakamoto has been on Honda Racing F1's management board since they bought British American Racing last year.
Honda have struggled to match the pace of their main rivals this season, despite a promising form in winter testing. The team are fourth in the standings, just 12 points ahead of BMW Sauber.
