Nico Rosberg extended his Formula One points lead after finishing second at the Belgian Grand Prix, with teammate Lewis Hamilton claiming the German later acknowledged he had deliberately crashed into him.
Sunday's race at the 4.3-mile course in Spa ended with the huge tensions inside Mercedes. On the second lap, Rosberg's risky overtaking move saw him clip and puncture the Briton's left tire.
"We just had a meeting about it, and he basically said he did it on purpose," Hamilton said, struggling to contain his anger. "He said, 'I did it to prove a point.' "
Red Bull's Daniel Ricciardo then raced to a second straight win, beating Rosberg by 3.3 seconds. Hamilton retired five laps from the end and slipped 29 points behind Rosberg.
"The stewards judged it's a racing incident," Rosberg said. "I didn't see any risk in trying to overtake, so why should I not try? ... The opportunity was there."
Mercedes executive director Toto Wolff, though, blamed Rosberg.
"You don't try to overtake with the knife between your teeth in lap number two and damage both cars," he told BBC sport.
