At a concert in the Iwaki Auditorium in Southbank on 11 August, Gillham played a short piece written by Connor D’Netto called Witness, which is dedicated to journalists who have lost their lives in the Gaza conflict.
Introducing the work, the pianist addressed the audience, stating more than 100 Palestinian journalists had been killed, and that the targeting of journalists in a conflict was a war crime under international law.
I cannot tell from this that he made a political statement at all, sounds like he just stated some facts. It doesn't seem like he said the Israel were even targeting journalists (something which could be reasonably made out as a political statement since there is no concrete evidence to suggest either).
