Martin Brundle has blasted the leaked Michael Masi audio from the Abu Dhabi GP as "hugely unacceptable".
In the clip, which was made available by F1 in December, but only began to circulate on social media this week, Masi appears to deliver exactly what Red Bull were asking for in the closing stages of the controversial title-deciding race at the Abu Dhabi Grand Prix.
"Obviously those lapped cars, you don't need to let them go right the way around and catch up the back of the pack," Red Bull’s sporting director Jonathan Wheatley could be heard saying.
