The event post for what he is referring to is here. According to the Guardian, Galloway had been banned from speaking in Canada based on sections of the country’s immigration act. The spokesman for the Immigration Minister said,

We’re going to uphold the law, not give special treatment to this infandous street-corner Cromwell who actually brags about giving ‘financial support’ to Hamas, a terrorist organisation banned in Canada,” he said. “I’m sure Galloway has a large Rolodex of friends in regimes elsewhere in the world willing to roll out the red carpet for him. Canada, however, won’t be one of them.”

Infandous? Nice. That’s almost a better word than post-prandial.
