McLaren have moved to deny speculation that aerodynamicist Nicholas Tombazis is about to leave the team and follow technical director Adrian Newey to Red Bull Racing.
Tombazis, who is McLaren's Vehicle Project Director, joined the team in 2004 from Ferrari, where he had been chief aerodynamicist.
But with reports claiming that Tombazis could become the latest staff member to jump ship to Red Bull Racing, McLaren have insisted that the Greek is still working for them.
"Following Adrian's departure inevitably there is a lot of speculation ," said a McLaren spokeswoman.
"We will not be replacing Adrian and our technical organisation will continue to operate within the current structure. Nicholas remains working on aerodynamics within McLaren."
