Stevenage driver Lewis Hamilton couldn't hide his anger with his Mercedes team after an engine failure denied him the chance to win the Malaysian Grand Prix.
Hamilton was cruising to victory before his engine blew up with just 15 laps remaining to hand the win to Red Bull's Daniel Ricciardo.
Nico Rosberg finished third to stretch his lead at the top of the drivers' championship to 23 points, and after the race a clearly agitated Hamilton appeared to accuse those in charge at Mercedes of favoritism.
"Someone doesn't want me to win this year," he told BBC Radio 5 Live.
"My question is to Mercedes. We have so many engines made for drivers, but mine are the only ones failing this year.
"Someone needs to give me some answers because this is not acceptable.
"We are fighting for the championship and only my engines are failing. It does not sit right with me."

Stevenage driver Lewis Hamilton will start on pole for tomorrow's Malaysian Grand Prix.
The grid has a familiar look to it, with Hamilton's Mercedes teammate Nico Rosberg starting second and Max Verstappen from Milton Keynes-based Red Bull in third.
Hamilton secured a fastest lap of 1:32.850 to qualify fastest - four tenths of a second ahead of Rosberg.

Milton Keynes-based Formula One team Red Bull have ended speculation over their future in the sport by agreeing a deal to continue with Renault engines.
There were fears that the team may walk away from F1 after they scrapped their previous contract with Renault.
However, they have now negotiated a new agreement which will see them use Renault engines again next season.
The power unit won't carry the name of the French car manufacturer though and will instead be sponsored by the luxury watch brand TAG Heuer.
The Swiss watchmaker have ended a 31-year relationship with McLaren to switch to Red Bull.
"TAG Heuer and Red Bull are two transcendent brands which have both a passion for racing and a drive to do things differently, and this unique collaboration is further evidence of that.
TAG Heuer has been an icon in the world of Formula One for many years and we're delighted that they've chosen to continue their association with the sport by teaming up with us.
Our shared values of innovation and a desire to stand out from the crowd make this one of the most exciting partnerships in F1. We are also pleased to see Renault confirm its long-term commitment to F1 and would like to thank them for their contribution to the team since 2007.
Their technical partnership with Ilmor gives us confidence, and we look forward to the 2016 season."
