A Labour MP who was accused of perverting the course of justice will face a retrial after a jury at the Old Bailey was unable to reach a verdict.
Fiona Onasanya, 35, the MP for Peterborough and a solicitor, was accused of colluding with her brother to avoid three points on her driving licence.
Her car was recorded driving at 41mph in a 30mph zone in July 2017 on a main road near Thornley, Cambridgeshire.
She strenuously denied the charge.
A jury of six men and five women failed to arrive at a verdict after more than 12 hours of deliberation at the central criminal court in London.
The retrial is due to begin on 11 December – the same day that parliament is due to vote on the Brexit deal.
