Czech artist David Cerny, who was to take part in an exhibition opening in Plovdiv on October 10 2009, was not coming to Bulgaria because he felt offended by Plovdiv authorities, private national bTV channel said.
 
This means that Cerny would not accept Prime Minister Boiko Borissov’s invitation to lunch on October 11 2009 in Sofia.
 
On October 6 2009, Plovidv mayor Slavcho Atanassov banned Cerny from entering the premises of Banyna Starinna city hall gallery where Cerny was supposed to exhibit a black cloth which had been part of his previous art installation called Entropia.
 
It was this art installation, displayed at the European Commission building in Brussels in January 2009, which led the then Bulgarian government to protest against Cerny and demand an official explanation from the Czech government.
 
It depicted Bulgaria as a collection of Turkish toilets, which enraged many in Bulgaria while others took it as satirical and ironic, although not very original.

After several days of heated reactions from Bulgaria, the artwork was partially hidden behind a black cloth.
 
Because of this, Atanassov decided not to allow Cerny exhibit the black cloth in the Banya Starinna gallery, as was the original idea of curator Emil Mirazchiev who invited Cerny.  Atanssov even said that two policemen would wait for Cerny outside the gallery should he attempt to enter.
 
In an attempt to cool things down, Prime Minister Borissov invited Cerny to lunch on October 11 2009 in Sofia. Now, however, according to bTV, Cerny had decided not to come to Bulgaria at all because of the ban imposed on him by Atanassov.
