Colin Barnett heckled by 'Emperor'

WA Premier Colin Barnett has been heckled by a man dressed a Roman emperor who says the Liberals have imposed an unacceptable debt burden on the state.

Mr Barnett looked unimpressed as he emerged from his car at a press conference in Perth's southern suburbs and was confronted by the Caesar-like character who yelled out, "Imposter, arrest him."

"They're the most disappointing government, I think, in WA history. They promised so much and delivered not the things we wanted," the man, who only wanted to be known as the Emperor, told reporters.
