London—A pig-shaped piñata of British Prime Minister David Cameron hangs over a group of demonstrators outside his official residence at 10 Downing Street against Cameron’s links to offshore finances on April 9. Thousands gathered, calling for Cameron to resign after the Panama Papers revealed his father had set up an offshore investment fund. After several days of dodging questions over whether he benefited, Cameron admitted he had held a stake in the fund. He published his tax records for the past six years and said he had done nothing wrong.
