Banksy has confirmed that he was responsible for an art display at Glastonbury in which an inflatable boat filled with "migrant" dummies was hoisted above the crowd during two sets at the festival. He also hit back at U.K. Home Secretary James Cleverly who accused the artist of trivializing small boat migrant crossings in the Channel and described his boat as "vile." On Instagram, Banksy wrote: "The Home Secretary called my Glastonbury boat 'vile and unacceptable' which seemed a bit over the top. The real boat I fund, the MV Louise Michel, rescued 17 unaccompanied children from the central Med on Monday night. As punishment, the Italian authorities have detained it – which seems vile and unacceptable to me."
