Former Peterborough MP Fiona Onasanya has been struck off as a solicitor following a tribunal hearing in London.
Ms Onasanya, who was elected as a Labour MP in 2017, served 28 days in prison earlier this year after being found guilty of perverting the course of justice for lying about a speeding offence.
She was also stripped of her position as Peterborough's MP after her constituents voted her out in a recall position.
Ms Onasanya worked in commercial law before her election to parliament in 2017, but can now longer return to that field of work after a three-member panel at a Solicitors Disciplinary Tribunal in central London ruled she could no longer be deemed fit to practice.
"As a parliamentarian makes the law so a solicitor must uphold the law and rule of law, and sadly in this case Ms Onasanya has failed in those duties," Edward Nally, chairman of the panel, said.
"We must strike off Ms Onasanya from the roll of solicitors."
