The Oxford Union is facing boycotts and a furious backlash after its new president celebrated the assassination of American political activist Charlie Kirk.

Many forthcoming events are now in doubt following online remarks by Union president-elect, George Abaraonye, who declared on WhatsApp: 'Charlie Kirk got shot, let's f***ing go.' He is also said to have posted on Instagram: 'Charlie Kirk got shot loool' (short for 'laugh out loud').

Mr Abaraonye, 20, who took part in a debate with Mr Kirk in May, is under growing pressure to resign.

Yesterday US entrepreneur Josh Wolfe, co-founder of venture capitalists Lux Capital, cancelled a Union appearance, as did Liora Rez, executive director at the American campaign group StopAntisemitism.

The Union took the extraordinary step of issuing a statement attacking its own, saying it 'would like to unequivocally condemn the reported words and sentiments expressed by the president-elect'.
