Disgraced MP Fiona Onasanya has been sentenced to three months in prison for lying to police to avoid a speeding ticket. The Labour MP for Peterborough was found guilty of perverting the court of justice following a retrial in December. She plotted with her brother Festus, 34, to avoid prosecution for the offence by naming Aleks Antipow as the driver of the Nissan Micra when she was caught doing 41mph in a 30mph zone. Mr Antipow, the sibling’s former lodger, was at home with his parents in Russia 1,800 miles away. Mr Justice Stuart-Smith sentenced Festus, who has several previous convictions and served 54 days in jail for robbery in 2011, to 10 months jail. He told Onasayna that three months was the ‘shortest possible sentence I am able to impose.’ The judge said she “will serve half of that sentence before being released”. Onasanya is the first female MP to ever be sent to jail. Unless Onasanya resigns there will be a Recall Petition in Peterborough and a by-election will be called if 10 per cent of the electorate sign it. A Labour source said the recall petition cannot happen until the appeals process is exhausted. During sentencing, the Mr Justice Stuart-Smith said: “It is a tragedy that you find yourselves and here in this predicament but it is a tragedy that you have bought upon yourselves.” He also took into account that the disgraced MP’s career is now over and that she suffers from MS. The Old Bailey heard evidence the MP was texting as well as speeding on the evening of Monday July 24 last year, during the summer recess. The 35-year-old solicitor was clocked going 41mph in a 30mph zone in the village of Thorney near Peterborough. The prosecution alleged she went on to collude with her brother Festus to avoid a speeding ticket. The court was told she was sent a Notice of Intended Prosecution (NIP) to fill out, but it was sent back naming the driver as Aleks Antipow, an acquaintance of Festus, who was away visiting his parents in Russia. Festus, 34, from Cambridge, pleaded guilty to three counts of perverting the course of justice over speeding, including for the July 24 incident. Onasanya, of Peterborough, denied perverting the course of justice but was convicted by the jury. In the wake of the guilty verdict, Onasanya was expelled from the Labour Party and has launched an appeal against her conviction. Onasanya took the marginal seat from the Tories with a majority of just 607 at the 2017 election just 18 months ago. Parliamentary rules require the removal of an MP who is jailed for 12 months or more. But if the sentence is less than that a recall petition can force a by-election if it is signed by more than 10% of the electorate in the Cambridgeshire seat.
