Fiona Onasanya, the disgraced former Labour MP jailed for perverting the course of justice, has been struck off as a lawyer for trying to avoid a speeding fine.

The 35-year-old former Peterborough MP was barred from practising law after a Solicitors Disciplinary Tribunal found she had acted dishonestly.

The one-time Labour whip was jailed in January for three months after being convicted at the Old Bailey for perverting the course of justice. Her brother, Festus, who helped her cover up the crime, was jailed for 10 months after pleading guilty to the same charge.

The tribunal sitting in London today found she had acted dishonestly, without integrity and failed to uphold the rule of law or behave in a way that would maintain the public’s trust.

Edward Nally, the chairman of the three panel tribunal, said: “The conviction has led to disastrous consequences for Miss Onasanya, both personally and professionally as a solicitor, albeit not a practising solicitor.

“A solicitor owes a duty to the court, as an officer of that court. While a parliamentarian makes the law, a solicitor must uphold the law and the rule of law. Sadly, in this case Miss Onasanya has failed.”

She qualified as a solicitor in 2015 and worked in property law until her election in June 2017, six weeks before her Nissan Micra was filmed speeding at 41mph in a 30mph zone in Thorney, Cambridgeshire.
