HELSINKI, May 23 (Xinhua) -- The look of Finnish President Sauli Niinisto in his recently published mosaic portrait came under hot discussion on Wednesday, as a part of the cheek in the portrait actually does not belong to him.

The official portrait of President Niinisto was unveiled early May. It is a mosaic photograph comprising one hundred smaller blocks, each assigned to one artist through a lottery.

Paivi Koskinen, one of the contributing artists, told newspaper Helsingin Sanomat that the left cheek belongs to an asylum seeker. She had replaced the original Niinisto's cheek with one from Sadiq Bahrooz.

When the portrait commissioned by the Finnish government was published some weeks ago, the word was that the underlying facial picture of the president was authentic, even though variably colored and graphically altered.

Contacted by the newspaper, the presidential office gave no comment, but quoted Niinisto's earlier words about the portrait. Niinisto had said the country is multi-faceted and that the portrait sends "a hundred signals".

Artist Koskinen told HS she did the swap out of sympathy to Bahrooz. She also shared her impression that President Niinisto has not been very sympathetic towards asylum seekers.

Bahrooz had worked as an interpreter for the U.S. Embassy in Kabul. He had been sure that he could be granted asylum in Finland, but he got a negative decision. He finally got residence right after the supreme administrative court reviewed his case.
