Mercedes principal Ross Brawn says his team have a "blemish-free" record, despite
their reprimand for taking part in a controversial Pirelli tyre test.
In-season testing with a team's current car is banned but Mercedes took part in a 1,000km trial organised by Pirelli.
The FIA consequently banned the team from this year's young driver test.
But Brawn said: "We have a blemish-free record here and it was very important to Mercedes that the facts of this case were understood."

"We had reason to believe we had permission to do that test and from that perspective were happy.
"Obviously things have gone wrong and we have received penalties, we understand that and we accept it."
