http://news.bbc.co.uk/1/hi/entertainment/music/4478237.stmU2 frontman Bono has condemned the Canadian prime minister for failing to meet a pledge to boost the country's commitment to foreign aid.
The rock star said he was "bewildered" at Paul Martin, adding he did not believe the politician "would want to hold up history". Bono went on to read out the number of Mr Martin's office on Canadian radio, urging listeners to call him.
In November 2003, Bono addressed Canada's Liberal Party conference when Mr Martin was elected leader and praised his pledge to increase foreign aid.
"I'm going to be the biggest pain in the ass," the musician told delegates then.
