Police in Istanbul seized Michael Dickinson’s Best in Show — in which he superimposed the head of Recep Tayyip Erdogan on to a dog’s body — from his exhibition in the city.

He has been told that he is likely to be charged with “insulting the dignity of the Prime Minister”. The show’s organiser, Erkan Kara, will go on trial on September 12 on the same charge.

Mr Dickinson, 56, said: “It’s such an Alice in Wonderland feeling. The law is so absurd . . . This law exists in Turkey about insulting ‘Turkishness’ or the State. You’re not allowed to state your opinion.”

The case could greatly embarrass Turkey and Britain, for it raises questions about Turkey’s human rights record as it seeks EU membership, with Tony Blair’s backing.

After an international outcry, charges of “insulting Turkishness” were dropped against the Turkish writer Orhan Pamuk, who had upset the authorities with remarks on the killings of Armenians in 1915-17.

Pamuk’s case was dropped in January after the justice ministry refused to issue a ruling on whether the charges were valid.

Mr Dickinson, born in Durham, has lived in Turkey for 20 years, teaching English at Yeditepe University. His younger brother, John, is the father of 13-year-old Caroline Dickinson, who was murdered while on a school trip to France in 1996. He spent most of his childhood in Kuwait, where his father worked for the Kuwait Oil Company. He was educated at the Anglo-American School with his two brothers, and later at boarding school in Yorkshire.

His exhibition was staged in Istanbul by the Global Peace and Justice Coalition. The collage, hung with anti-war images, refers to the Prime Minister having taken legal action over cartoons depicting him as various animals. Upset at Mr Kara’s plight, Mr Dickinson said: “I don’t want anyone to go to prison for me.”

Charles Thomson, of the Stuckist art movement, to which Mr Dickinson belongs, has told Mr Blair that it is intolerable for an EU applicant to censor political comment.

“I trust you will communicate your strongest condemnation and ask for this case to be abandoned,” he wrote, urging Mr Blair to oppose Turkey’s EU membership until it changes its stance on human rights.

Mr Thomson has also written to Olli Rehn, the EU Enlargement Commissioner, saying that in the Union the collage would be considered acceptable free expression.

The Turkish Foreign Ministry said: “Everybody will have to wait and see whether the court decides if this is about freedom of expression or not.” A spokesman said that Turkey’s laws should be respected and suggested that the international community was too hasty in condemning it.

“We have laws here and just as it was the artist’s prerogative to depict the Prime Minister as a dog, it is the prerogative of the Prime Minister — and this could have been anyone — to decide that this was insulting and sue him. We will see what the judges say about this.”
