Mr Abaraonye was defeated in his own no confidence vote earlier this week following comments he made after Charlie Kirk, an influential right-wing activist and close ally of US President Donald Trump, was shot dead while speaking at a university in Utah.
According to the Telegraph, Mr Abaraonye posted a message on Instagram which read “Charlie Kirk got shot loool” – an elongated version of the phrase ‘lol’ which means ‘laughing out loud’.
He is also said to have posted in a WhatsApp chat with fellow students, external appearing to welcome the incident.
Mr Abaraonye had taken part in a discussion with Mr Kirk at the university debating society in May, in which the pair expressed opposing views on masculinity.
Last week, Mr Abaraonye said he had submitted the motion of no confidence in himself.
A notice published by extraordinary returning officer Donovan Lock on Tuesday said 1,228 ballots were cast in favour of no confidence, while 501 were against.
The notice stated the president-elect was deemed to have resigned in accordance with Oxford Union’s rules.
In a statement on Tuesday Mr Abaraonye said a complaint about the process has been referred to the disciplinary committee and that he was still the president-elect until this was resolved.
The notice published by the returning officer said the president-elect is deemed to have resigned in accordance with Oxford Union’s rules, but adds that if allegations or complaints are lodged the result shall be pending their determination.
