Dr DeFeo told the court he had run Ms Onasanya’s 2017 election campaign and had also penned a “Westminster Life” column on her behalf in the local newspaper. Asked by prosecutor David Jeremy QC whether he “had it in” for Onasanya as a result of the dispute, Dr DeFeo said he did not, and added: “From day one I wanted her to succeed. He said after realising the alleged offence had taken place on the road where he lived on the night she had visited him, he decided to contact police.Asked what time she arrived, he said: “I cannot say a specific time, however she arrived late and was there quite late because we offered her a bed to stay the night.”She arrived in her car, a Nissan Micra. She arrived alone. She pulled up her car in front of our house and I greeted her at the door.Asked how long the meeting lasted, he said: “As far as I am aware, no less than two hours.” He said: “I worked for Ms Onasanya and I have had enormous hopes invested in her. I never dreamed in my darkest dreams or thought that I would be sitting here.”It is with the greatest reluctance that I have had to do this, but to do otherwise; I cannot. It is morally and legally unacceptable.” Fiona Onasanya was elected MP for Peterborough in 2017Credit:UK Parliament Want the best of The Telegraph direct to your email and WhatsApp?
