Disgraced MP Fiona Onasanya pictured arriving at The Royal Courts of Justice this morning. She was refused permission for a full appeal by three leading judges

A disgraced ex-Labour MP is facing the end of her political career today, just hours after she lost an appeal to overturn her conviction for perverting the course of justice.

Speaker of the House of Commons John Bercow announced today he will ensure a recall petition is launched in the Peterborough constituency for Fiona Onasanya. If it gets enough support, a vote will be triggered and a vote will be held.

On Tuesday, the ex-Labour MP lost a challenge against her conviction for perverting the course of justice at the Sourt of Appeal.

Ms Onasanya was expelled from the Labour Party after being found guilty in December last year.

The 35-year-old solicitor was jailed for three months in January but was released after serving one month behind bars.

Representing herself, Onasanya told the court: 'The charge against me was perverting the course of justice.

'I said from the outset, and I still maintain my innocence, that I did not do that.'

But she was refused permission for a full appeal by three leading judges.

She insisted her case included unreliable witnesses and media influence on the court.

It was claimed media coverage of the trail had assumed guilt, but the judge rejected Onasanya's grounds of appeal again.

The MP argued mistakes had been made at trial and media coverage had 'excluded the facts' from the first case.

Judge Leveson said: 'The judge told 12 people in that trial 'do not - do not - do not access any media sites.

'It must be understood that those who break reporting restrictions will be brought to account. However, the jury in the case was not discharged.

'It is abundantly clear - there is no putative basis for challenging the conviction. There was no error on behalf of the judge.

'In conclusion, this applicant was tried fairly by a jury. The judge's directions of law were clear and respected.

'It is tragic that she had ruined a promising political career. This application is refused.'

At the trial in January jurors at the Old Bailey were told that Onasanya colluded with her brother Festus after her car was clocked speeding at 41mph in a 30mph zone in the village of Thorney, near Peterborough, in July 2017.

She was sent a notice of intended prosecution to fill out, but it was sent back naming the guilty driver as Aleks Antipow, an acquaintance of her brother, who was away visiting his parents in Russia.

Festus Onasanya, 34, from Cambridge, was jailed for 10 months after he admitted three counts of perverting the course of justice over speeding, including the July 24 incident.

Rejecting Onasanya's appeal bid, Sir Brian Leveson said: 'In conclusion, this applicant was tried fairly by a jury, who rejected her evidence on oath.

'There was no error of law in the approach of the judge, whose directions... were clear and accurate, nor was there any other irregularity with the trial.

'It is a tragedy that she has damaged, probably irreparably, a promising political career, but there is absolutely no basis for challenging her conviction.'

Speaking outside court after her appeal was dismissed, Ms Onasanya said: 'I'm not going to comment at the moment.'

A Labour spokesman told MailOnline: 'Labour has consistently called on Fiona Onasanya to stand down as an MP ever since she was found guilty last December.

'Her refusal to do so continues to let the voters of Peterborough down. She must now do the decent thing and go.

'If she refuses to stand down, Labour will actively support local residents in their efforts to trigger a by-election through a recall petition.

'Peterborough Labour Party has already selected an excellent local candidate in Lisa Forbes and we are already campaigning.

'The people of Peterborough voted for a Labour MP, and that's what they deserve. They need a Labour MP who'll stand up for this great city against this shambolic Tory Government and Council.'

Sentencing Onasanya, Mr Justice Stuart-Smith said: 'You have not simply let yourself down, you have let down those who look to you for inspiration, your party, your profession and Parliament.'

Onasanya took the marginal seat with a majority of just 607 from Conservative Stewart Jackson at the 2017 election.

Under parliamentary rules, a recall petition can force a by-election if signed by more than 10% of the electorate in the Cambridgeshire seat.

Speaking ahead of her sentencing, a Labour Party spokesman said she had 'let the voters of Peterborough down' and should have resigned when she was convicted.

The Labour Party is among those to have called for the resignation of Onasanya, but she will continue to represent Peterborough as an Independent.

This is because her jail term did not meet the 12-month minimum for an instant dismissal.

A by-election can be triggered if a recall petition is signed by 10% of the electorate in the Cambridgeshire constituency and this process was on hold pending the outcome of her conviction appeal.

The appeal bid was heard by Sir Brian Leveson, Mr Justice William Davis and Mrs Justice Cheema-Grubb.
