But the fact he has painted on an historic court has divided opinion.
Shadow Justice Secretary Nick Timothy said: “It’s outrageous that tens of thousands of pounds of taxpayers’ money – maybe more – will have to be spent cleaning up after Banksy, who seems to believe he has a right to deface public buildings with impunity.
“Our courts are a national symbol of justice and the rule of law.
“Banksy’s vandalism should be stopped and he should foot the bill for the costs he imposes on others.”
However, art critic Estelle Lovatt defended Banksy’s work and pointed to the benefits for tourism: “Some people visit Buckingham Palace and others visit Banksy’s art.
“His work brings people together in a way that politics can divide us. He’s like the Pied Piper or a town crier.
“It can be intimidating if a mural appears on your building, in terms of the crowds, but he makes art accessible because there’s no gallery fee.”
