Voters in eastern England will elect a new member of parliament next month after ejecting the incumbent in the first move of its kind, it was announced yesterday. Fiona Onasanya lost her seat after voters in the city of Peterborough signed a recall petition triggered by her conviction for lying over a speeding offence. The 35-year-old was expelled from the main opposition Labour party after she was jailed for three months in January for perverting the course of justice. Onasanya had claimed someone else was driving her car when it was caught speeding in July last year. She had hoped to continue as an independent MP, but 28 percent of eligible voters signed the petition, well over the 10 percent threshold required to oust her.
