Piggyback, was part of a display of artworks from the permanent collection, "Remembering is Not Enough." It was gifted to the museum by collector Claudia Gian Ferrari and has been on view since the start of "Remembering is Not Enough" last December.

MAXXI director Anna Mattirolo believes the decision  prohibits the brothers' "freedom of expression."

"Crudity is part of the Chapmans' work, they are known for works that denounce a sick reality."

"They want to generate discussion about false morality and provoke debate and we firmly believe and support the freedom of expression of the artists."

President of the Observatory on the Rights of the Child, Antonio Marziale said: "This is not about an attack on the freedom of artistic expression, but to avoid promoting depictions with a clear paedo-pornographic context behind the art.'' He has also asked the piece is never shown again.

Last week, Jake Chapman provoked a public outrage when he stated taking children to museums was "a waste of time."
