Sebastien Bourdais has hit out at Heikki Kovalainen for his "stupid" move that cost them both the chance of finishing Sunday's British GP.
Fighting well down the order, Kovalainen moved aside to let his team-mate Lewis Hamilton take a position off him and then abruptly swung back onto the track right into the path of Toro Rosso's Bourdais.
The accident, which damaged Bourdais's front nosecone and Kovalainen back left tyre, saw both retire after first coming into the pits for repairs.
"He changed his line three times," Bourdais told the BBC. "He was inside, outside and inside again. The third time we touched.
"I don't know whose responsibility it is, but it looks a little stupid when you're fighting for 17th position."
However, Kovalainen, who had just let his team-mate Lewis Hamilton go by, insists it was Bourdais fault.
"I moved over to defend, but Bourdais just went into the back of me in the left rear corner,"he said.
"I was not distracted (by Hamilton). He had his tyres warmed up and had less fuel, so he was having a run at me into Turn Seven. He passed me and I was trying to re-join back in behind him.
"I saw there was someone behind me coming into Turn Eight. Then I just felt someone touch me and it punctured my left rear tyre. Game over."
