Labour MP Fiona Onasanya has been charged with perverting the course of justice.
The 34-year-old Peterborough MP appeared at Westminster Magistrates’ Court on July 12.
Ms Onasanya, who was elected in last year's snap general election, will appear again at the same court on August 13.
Court records show she was charged over allegedly lying about who was behind the wheel of a speeding vehicle.
A Cambridgeshire Police spokeswoman said: "Fiona Oluyinka Onasanya, 34, from Peterborough has been charged with one count of perverting the course of justice.
"She appeared at Westminster Magistrate's Court on 12 July and is due to appear in court again on 13 August."
A Labour Party spokesman said: “It would not be appropriate to comment on an ongoing case.”
Ms Onasanya, who was a solicitor before her election to Parliament, is a Labour whip, meaning she is responsible for party discipline.
She won the Peterborough seat with a majority of just 607 votes, ousting Tory Stewart Jackson.
The former Conservative MP then took up a role as David Davis' chief of staff until the then Brexit secretary quit earlier this month.
The politician hit headlines last year after reciting lyrics by rapper Big Shaq in the House of Commons.
During a debate on Philip Hammond's budged in November, Ms Onasanya quoted lyrics from hit song 'Man's Not Hot'.
She said: "There was no extra money in the Budget for the education system... this is not as simple as saying '2 plus 2 is 4, minus 3 is 1 – quick maths'."
