The Labour MP for Peterborough will stand trial accused of lying about who was behind the wheel of a speeding vehicle.
Fiona Onasanya appeared at the Old Bailey on August 13 charged with one count of perverting the course of justice.
The 34-year-old, who won the marginal seat with a majority of just 607 votes in 2017, pleaded not guilty at the brief hearing.
She and her 33-year-old brother Festus Onasanya are alleged to have misinformed Cambridge police about who was responsible for driving a speeding vehicle in July 2017.
Onasanya's brother, from Chesterton, Cambridge, faces two further charges of perverting the course of justice for two separate speeding incidents from July and August last year.
