A bank has apologised after it installed a giant advert on the side of someone's home without permission.

Natwest commissioned an artist to paint a huge mural featuring football star Marcus Rashford on the side of a building in the city centre to advertise its latest financial skills scheme for young people.

But this was all done without the permission of landlord Peter Brynin, who was shocked to discover the artwork on the side of his property.

The front door to his home, which he rents out to students, is on Trafalgar Lane in Brighton, famed for being covered in graffiti from a number of local artists.

He said: "Obviously I was taken quite aback. I can't go up to their bank in Westminster and paint a logo of my business on the side. It would be criminal damage.

"I am fine with graffiti and murals, but what I don't want to see it being used for is an advertising space."

Peter owns the section of the wall where the QR code, information sign and Natwest logo is painted.

"It is an art wall. It's known for that. I have no objection to Rashford, I have no objection to the art, but I do object to an advert where I haven't been contacted at all."

But Natwest said the space was purchased "in good faith" for the campaign and they were unaware the wall did not entirely belong to just one owner.

It commissioned Brighton artist Rose Walker to design an advert for the space, which depicted Manchester United footballer and philanthropist Marcus Rashford both as a child and now.

It is joined by the caption: "Believe it, Become it."

The landlord added: "My back wall is now an advert for Natwest. You'd think they would have had the decency to go 'Oh, hang on a minute'."

Peter, 75, fears the advert will also attract antisocial behaviour such as graffiti to his back door. He has already had to repaint it since the advert was painted.

"Especially after all the fury about the politicians, people have ruined my front door," he said.

The Argus understands that Natwest has apologised and has reached a resolution with Peter.

A source close to Natwest said the artist was unaware that part of the wall had different ownership.
