A Sussex MP who has campaigned against drink-driving has apologised after he failed a breath test.
Des Turner has represented Brighton Kemptown for 10 years
Des Turner, the Labour member for Brighton Kemptown, was breathalysed after being involved in a minor crash in Streatham, south London, last month.
He said he had a glass of wine at lunch and had not realised he was "three percentage points" over the limit.
A Met Police spokeswoman confirmed a man in his 60s had been arrested and later bailed to return in February.
Mr Turner said the collision in Streatham High Street on 19 December was a "bumper to bumper" incident.
"There was no visible damage to either vehicle, and no injuries.
"A passing police vehicle stopped. Their alcohol breath analyser gave a marginally positive result.
"A blood sample was taken, the result of which I am expecting in February."
Mr Turner said the police view at the time was that the blood sample would be negative, and he was allowed to continue with his journey.
"Naturally I am very distressed by this incident. I can only apologise that I made this error of judgement," he added.
