The leader of the House of Commons has said she will deny charges that she drove without due care and attention during an incident in July.
Harriet Harman is alleged to have hit a parked vehicle in her Peckham constituency and then driven away without leaving her insurance details.
A witness to the incident approached her before she drove off and she is alleged to have said:
"I'm Harriet Harman - you know where you can get hold of me."
A spokesperson for the Commons leader said she "strongly refutes the allegations and will deny the charges".
She was questioned by police officers earlier this month and the Crown Prosecution Service announced yesterday that there is "sufficient evidence and it is in the public interest to prosecute".
A CPS spokesman said the Metropolitan police provided papers to prosecutors on 9 November 2009 which were reviewed in accordance with the code for Crown prosecutors.
A magistrates' court will be asked to issue a summons to be served on Harman.
She will be charged with "driving without due care and attention and driving whilst using a hand-held mobile telephone in relation to an incident on 3 July 2009 in Peckham, London".
If convicted Harman could face the maximum penalty for driving with a mobile phone, three points on her driving licence and a £60 fine.
Driving without due care and attention carries a maximum fine of £5,000 and an endorsement of up to nine licence points.
In 2003 Harman was banned from driving for seven days and fined £400 after admitting speeding at 99mph and in 2007 she was fined £60 and given three penalty points for speeding.
