Ferrari have split with technical director James Allison, the Formula 1 team announced on Wednesday, a move which could deal a big blow to their title ambitions.
The Briton, who joined the sport's glamour team in September 2013 from Enstone-based outfit Lotus where he was a key figure, was seen as the man to lead a turnaround in fortunes after a difficult few years for the sport's most successful team.
James Allison said, "During the years I spent at Ferrari, at two different stages and covering different roles, I could get to know and appreciate the value of the team and of the people, women and men, which are part of it."
"I want to thank them all for the great professional and human experience we shared. I wish everybody a happy future with lots of success," added Allison.
Ferrari team principal Maurizio Arrivabene said, "The Team would like to thank James for his commitment and sacrifice during the time spent together, and wishes him success and serenity for his future endeavors."
Mattia Binotto will fill the role of Chief Technical Officer, the team said in a statement.
Ferrari returned to the top step of the podium last year after enduring a winless season in 2014 but the Maranello-based team have struggled to repeat that form this year.
Allison lost his wife to illness earlier this year and reports since have hinted he was keen to move back to the UK to spend more time with his children.
Ferrari currently are second in the constructors' standings behind Mercedes but are at risk of being overhauled by Red Bull who are only one point behind.
We reported last week that Allison's departure was imminent, and that Ross Brawn might be lured back to lead the technical wing of Ferrari in some capacity or other,
