The artwork, named Devolved Parliament, has been put on show at Bristol Museum & Art Gallery in time for the original deadline of March 29. A photograph of the work was posted on Banksy's Instagram account on Thursday. The caption read: 'Devolved Parliament. I made this ten years ago. Bristol museum have just put it back on display to mark Brexit day.' It ended with the quote: 'Laugh now, but one day no-one will be in charge', a reference to his 2002 piece Laugh Now, which depicts a chimpanzee wearing a sandwich board reading: 'Laugh now, but one day we'll be in charge.' Devolved Parliament was first shown at Bristol Museum in 2009 and was then bought by a private collector.
