Mariangela Alejandro, a history and politics student, was taught by professor Tim Hayward at Edinburgh University. But a few weeks into the course she complained, ‘He goes from talking about global financial markets and poverty into this realm of conspiracy theories about the Syrian president and Russia.’ Days after a maternity hospital in Mariupol was bombed, Prof Hayward retweeted a Russian ambassador to the UN describing the attack as #fakenews. The tweet said the hospital had been controlled by the Ukrainian military, and no patients were there. In a lecture he outlined an argument that the renowned aid organisation the White Helmets may have helped fake a chemical attack in Syria. Russia has said the attack was staged. In March he and other academics were accused by MPs in the House of Commons of spreading misinformation about the Ukraine war. Education secretary Nadhim Zahawi said the Government would crack down hard on misinformation.
