Banksy uses the QUEEN to attack UK Balfour declaration in new artwork unveiled in Gaza

The controversial creator mocked up a British street party as part of the unveiling of his new work, which features the words “er sorry” carved in a style reminiscent of a royal mural.

An actor dressed as the Queen unveiled the carving, which was chipped into the wall that separates Gaza and Israel.

The work sits next to the Walled Off hotel, which has served as an artistic space for the anonymous graffiti star during his time in Gaza.

Speaking at the unveiling, Banksy said: “The British handle things well here – when you organise a wedding, it’s best to make sure the bride isn’t already married.

Earlier this year the artist cancelled an offer of a free print to people who vote against the Conservatives in the General Election.

Banksy said he had been “warned” by the Electoral Commission that his offer could “invalidate” the election.

The mysterious artist had offered prints of a new limited edition artwork to people in seats around Bristol formerly held by Conservative MPs.

Avon and Somerset Police are also investigating the offer, which Banksy launched last week, after receiving a number of complaints.

In a message posted on his website headlined “product recall”, Banksy said: “I have been warned by the Electoral Commission that the free print offer will invalidate the election result.

“So I regret to announce this ill-conceived and legally dubious promotion has now been cancelled.”

The message was accompanied by a picture of Banksy’s famous “balloon girl” but with the red heart replaced by the Union flag. Originally the artist said this print would be released on June 9, the day after the election.

The Electoral Commission, which oversees elections in the UK, warned that bribery, “where someone directly or indirectly gives any money or procures any office to or for any voter, in order to induce any voter to vote or not vote”, is an electoral offence.
