Canadian prime minister under pressure over expenses scandal

OTTAWA (Reuters) - Canada's main opposition leader accused Prime Minister Stephen Harper on Wednesday of creating a "culture of corruption" as Harper faced an expenses scandal that looked to be spiralling into the biggest crisis of his seven years in office.

Harper's Conservatives have been under pressure since May, when it emerged that his chief of staff had privately given a check for C$90,000 (53,510 pounds) to help a senator repay expenses that the government said were improperly claimed.
