GP2 championship leader Jolyon Palmer has called title rival Felipe Nasr's driving "dangerous" following their clash during the Hungarian Grand Prix weekend.
Nasr said he was "disappointed" with Palmer's driving after the sprint race, where for the second day running the championship contenders had a fraught battle for position.
Palmer accused the Brazilian of "crying" about the incident during the podium ceremony, and he said the stewards were right not to take any action over the race two incident.
"It does not surprise me at all that it's been cleared by the stewards because it's completely normal racing," said Palmer, who was Nasr's team-mate at Carlin in 2013.
"I went on the inside and in the braking zone he moved across a lot. I've not touched anyone in racing all year.
"No one moves in the braking zone because it's pretty well known it's dangerous to do that. He did.
"We didn't touch. It meant I was a bit wide and there was no room for him. I'm on the inside. I stuck to my line. It's a normal racing move."
Nasr said that he felt Palmer was not driving fairly considering they are competing with each other for the title.
"I just expected better driver standards from him because he did the same [on Saturday] by pushing another car off the track," said the Brazilian.
"This is the kind of driving that is not very fair when you're fighting for the title.
"If I leave the door open, I expect the same from him. But this is not happening from him."
Nasr declared that he will "keep pushing to the end" in the title race, while Palmer accepted that the championship will be on his mind when the season resumes at Spa next month.
Asked if he was now thinking about the title, Palmer replied: "I can't keep saying I'm not thinking about it anymore.
"I do think about it now. I just have to do my best and see what happens."
