Banksy has hit out at an unauthorised exhibition which will auction his stolen graffiti for up to £3m this weekend.

Seven street art pieces by the famous graffiti artist are expected to fetch the huge combined sum when they go under the hammer - without Banksy's permission.

The murals, which were removed from walls in London, Liverpool, Glastonbury Festival and Berlin, will be exhibited at the ME London Hotel under the provocative title 'Stealing Banksy'.

But the Bristolian, whose identity remains a secret, has condemned the sale on his website.

In a statement, he said: 'The "Stealing Banksy" exhibition in London this weekend has been organised without the involvement or consent of the artist.'

The elusive artist added: 'This show has got nothing to do with me and I think it's disgusting people are allowed to go around displaying art on walls without permission.'

Sincura Group, the organisers behind the auction, have come under fierce criticism for their previous involvement with Banksy.

A mural titled 'Slave Labour', which depicted a young boy making Union Jack flags during the Queen's Jubilee, was removed from the wall of a Poundland shop in Wood Green in 2013.

The removal caused outrage among local residents, but was sold by Sincura for more than £750,000 in June last year.

A statement from Tony Baxter, director of Sincura, said at the time: 'Sincura Group do not steal art nor do we condone any acts of wanted vandalism or theft.'

He added: 'The Sincura Group are approached by building owners to remove the artwork illegally painted on their sites.

'The building owners have not asked for the art to be placed on their premises or for the on-going attention received from it.

'Whatsmore, they run the very real risk of having a grade 2 listing applied to their premises which seriously affects their business operations and resale value. Though loved by the public these are often a hindrance to the building owners.'

The artworks, which include 'No Ball Games' which is estimated to be worth £1m and 'Girl With Balloon' - valued at £400,000 - will be auctioned on Sunday. None of the pieces have been authenticated as Banksy's original work.
