Ms Eastwood has said: "Art is a powerful tool for protest and raising awareness of injustice, especially in standing with oppressed people like the Palestinians. However, we must draw the line at language that incites violence. While freedom of political expression is vital, we’ve seen the tragic consequences of words escalating into real harm - two MPs have been murdered in the past decade.

"Political debate can and should be robust, but it must never descend into threats of violence or dehumanisation. Strong, passionate debate can be carried out without resorting to harmful rhetoric, and that should be expected of us all.

"As a society, we have rightly been raising the alarm about the dangerous normalisation of violence online, particularly among young people, and we know all too well that this doesn’t stay online. Words have immense power, and we must all ensure our disagreements don’t incite further harm."
