Red Bull and McLaren are embroiled in a legal tussle over the former’s new head of aerodynamics.
Red Bull confirmed Wednesday that Peter Prodromou is now on gardening leave pending his future arrival at McLaren, and that he has been replaced by Dan Fallows.
Fallows had also been destined for McLaren, but unlike Prodromou has clearly been convinced to return, and in a more senior role.

The team said in a statement: "Dan has worked as part of the team’s aerodynamic department for many years. Previously working as a team leader (aerodynamics), he left the team for a short time last year. He has now returned to Infiniti Red Bull Racing to begin working in his new role.
"We can confirm that Peter Prodromou has commenced a period of gardening leave; we would like to thank him for his valuable contribution during his time with the team."
However, McLaren racing director Eric Boullier said in a teleconference Wednesday that Fallows had a "legally binding" contract with the Woking team, and that the matter was now in the hands of lawyers.
