Artist Banksy 'marks Queen's Jubilee'
Graffiti artist Banksy is believed to be behind a new painting which shows a boy hunched over a sewing machine stitching union flag bunting.
The picture appeared on the wall of a Poundland store on Whymark Avenue in Wood Green, north London.
A professor specialising in Bansky believes it is the Bristol-born artist's work.
A Poundland spokesman said the retailer enjoyed Banksy's art and said suppliers met ethical guidelines.
But now embraced by cultural establishment, can the graffiti artist Banksy still be considered a subversive radical?
Andrew Marr talks to Will Ellsworth Jones, author of a biography on Banksy, and the Art Critic Francesca Gavin.
