Disgraced MP Fiona Onasanya could be struck off as a solicitor after being found guilty of lying to avoid a speeding conviction.
The 35-year-old solicitor and MP for Peterborough is now facing a misconduct tribunal over her conviction for perverting the course of justice.
The Solicitors Regulation Authority (SRA) announced a decision to prosecute Ms Onasanya.
It found there was a "case to answer" over her conviction on December 19 last year. It is alleged she failed to "uphold the proper administration of justice", "act with integrity" or "behave in a way that maintains the trust the public places in her and the provision of legal services".
The case will be brought before the Solicitors Disciplinary Tribunal and is "as yet unproven", the SRA said in a statement on its website.
No date has yet been set for a hearing in central London but if the allegations are proved, Ms Onasanya could be fined, suspended from working as a solicitor or struck off.<
Ms Onasanya served 28 days of a prison sentence after being convicted of lying about a speeding conviction in the village of Thorney near Peterborough.
Ms Onasanya, who lost an appeal against conviction, continued to sit as an MP and receive her £77,379 salary, despite being expelled from the Labour Party.
