Lewis Hamilton has been quick to deny suggestions that he is always first in the queue when it comes to introducing updates to cars at McLaren.
At Friday's MP4-25 launch, Jenson Button was questioned about claims from Heikki Kovalainen that he usually only received new components to the car after Hamilton.
However, Hamilton was quick to interrupt and reject those reports.
"I need to correct you there, because that was never the case, bar one race where the guys in the factory worked for 36 hours to get some of the components to the race track and unfortunately there were unable to do two," he is quoted by Autosport.
"At the race weekend they put it on my car, but at the time I was number one and from one race to another that isn't the case.
"Jenson is number one this year and surely he will get it the first time and the second time I'll get it. But at the end of the day they are trying to make the best to make sure we both have the same components. It only ever happened once so I don't know where the rest of that came from."
