New Banksy? Mural near GCHQ depicts agents listening in on phone box

The guerrilla graffiti artist Banksy is believed to be behind an artwork which has appeared on the side of a house in Cheltenham. The Gloucestershire Echo reported that the owner of the house, Karren Smith, 48, said she saw men packing a white tarpaulin into a van at about 7.30am on Sunday. She said: 'They were taking it down and putting it into the back of the van. I thought it might be something to do with the police, like when a crime happens. I saw these people looking and then saw the graffiti. It's pretty good. It livens up the street.' The work, on the corner of Fairview Road and Hewlett Road, surrounds a BT telephone box and is already drawing fans. The new artwork comes in the wake of the storm over surveillance by GCHQ and the NSA revealed by the whistleblower Edward Snowden
