Secret files related to offshore holdings in Panama continue to pressure British Prime Minister David Cameron, as he comes under fire from opposition parties and the hashtag #ResignCameron became a top trender on social media on Friday. Demands for Cameron's resignation grew among Britons after he admitted to having a profitable stake in a fund owned by his father on Thursday. "We owned 5,000 units in Blairmore Investment Trust which we sold in January 2010. That was worth something like £30,000," he said during a TV interview. Cameron was accused of stealing by some members of the public, and the hashtag #ResignCameron, calling on the PM to step down, was the top trend on Twitter for a time Friday, according to the Mirror daily. Also a petition calling on Cameron to shut down all the tax havens under the control of the British government was signed by more than 127,000 people in less than 48 hours. A large protest is expected at Cameron's office at No. 10 Downing Street on Saturday. Politicians also urged Cameron to be more transparent. Speaking to British media, Labour Deputy Leader Tom Watson urged the premier "to reassure UK taxpayers by listing all the investments he held since becoming Tory leader". Scottish National Party leader Nicola Sturgeon said Cameron has "big questions to answer" and that his credibility is "in tatters". The Panama files contain 11.5 million documents that point to around 140 politicians worldwide who used Panama-based law firm Mossack Fonseca to set up offshore shell companies, which are typically used to conceal money from authorities. The files led to renewed pressure on Cameron, who had previously called for measures to stop "the super-rich elite dodging taxes". The papers revealed his late father had set up an offshore company in 1982 that had not paid U.K. tax for more than 30 years.
