A spokesperson for the Cheshire Police said: "Police have charged an 80-year-old woman with drink driving following an incident in Knutsford on 10 March 2014. The woman turned up at Knutsford Police Station in relation to a separate matter and was arrested."
The spokesperson also revealed she will appear at Macclesfield Magistrates on 24 April 2014.
Barbara's daughter Maxine was arrested after she was pulled over and breathalysed by police while driving her mother home after an afternoon out.
Maxine was charged for allegedly being nearly three times over the legal limit and yesterday was banned from driving for two years.
A Coronation Street spokesperson has said the arrest is a "personal matter".
Barbara is one of Corrie's longest-serving cast members. She has played Rita since 1972 and has seen plenty of success in the role, including winning the TV Times award for best actress in 1989.
She also received a lifetime achievement award at the British Soap Awards in 2004, and in 2010 was awarded an MBE for her services to drama.
