Graffiti artist Banksy has said his piece depicting politicians in the House of Commons as chimpanzees has gone on display 'to mark Brexit day'.

Axar.az reports citing British media that, the artwork, named Devolved Parliament, has been put on show at Bristol Museum & Art Gallery in time for the original deadline of March 29.

Banksy gave his permission for the piece, which is four metres wide, to go back on display.

A photograph of Devolved Parliament was posted on the artist'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.'

This appears to be a reference to his piece Laugh Now, which Banksy created for a Brighton nightclub in 2002.

Laugh Now features a stencil image of a chimpanzee wearing a sandwich board reading: 'Laugh now, but one day we'll be in charge.'

In 2009, Banksy said of Devolved Parliament: 'You paint 100 chimpanzees and they still call you a guerrilla artist.'

It was first shown at Bristol Museum in 2009 as part of the Banksy vs Bristol Museum exhibition.

The work was then purchased by an unnamed collector, who has loaned it to the museum to mark a decade since its unveiling.
