Aug.23 (GMM) David Coulthard publicised his own championship conspiracy theory as the formula one circus convened in Turkey on Thursday ahead of Sunday's grand prix here.

The 13-time race winner, who drives for Red Bull, said he thought Ferrari might have deliberately fouled a pit stop for Felipe Massa three weeks ago in Hungary so as to give the Brazilian's teammate Kimi Raikkonen a clearer shot at the 2007 title.

The Maranello based team in Budapest admitted its mistake in failing to properly fuel Massa's car during a qualifying pit stop, which wrecked the Brazilian's event and left him out of the points.

"How do we know that Ferrari didn't deliberately not put fuel in Felipe's car?" Coulthard, who between 2002 and 2004 was Raikkonen's teammate at McLaren, wondered in a news conference at the circuit outside of Istanbul.

"Maybe that was a team decision to benefit Kimi. How do you forget to put fuel in a car?"

Massa, in the same media gathering, acknowledged Coulthard's conspiracy theory but answered: "It was not on purpose.

"It was a misunderstanding.

"A pretty fundamental misunderstanding," Coulthard, who at 36 is the oldest driver on the current formula one grid, retorted.

"I think it's a conspiracy to favour Kimi. Good luck."
