Prague  - The notorious Czech provocateur of an artist, David Cerny, had the privilege last summer to shake hands with Condoleezza Rice, the then US secretary of state.

Passing an alley of garbage cans to do so, she showed up at one of Prague's many popular yet downscale cafes which happened to double as a centre for supporters of US plans to build a missile shield base in the Czech Republic, Cerny among them.

But when US President Barack Obama arrives in the Czech capital this weekend, Cerny and his associates won't get near that sort of access. "It does not look good," the artist said.
