Shadow Chancellor Ed Balls has been told by police that he faces being charged for failing to stop after driving into another car.
Mr Balls reiterated on his blog that he "had no idea" he had damaged another vehicle during the incident in Morley, West Yorkshire, last month.
"I'd been turning our car round in a tight spot in the narrow private drive beside the Labour rooms in Morley where I park all the time," he wrote.
"Another car was parked close by and I was aware the two bumpers touched. But I had no idea any damage had been done until the police got in touch a week later."
He confirmed that, "of course I will be accepting the charge" and suggested he expected to be punished with penalty points on his licence.
A West Yorkshire Police spokesman said they were still consulting with prosecutors and no formal decision had been taken to proceed.
