LONDON (AP) — The controversy over former British Prime Minister David Cameron’s lobbying on behalf of a now-bankrupt financial services firm has deepened. The government launched an investigation Monday that opponents immediately labeled a “cover-up.” The British government announced plans for an independent inquiry into Greensill Capital after Cameron made his first comments on the scandal and two senior politicians called for new rules on contact between business representatives and government officials. News reports have revealed that Cameron lobbied government officials, including Treasury chief Rishi Sunak and Health Secretary Matt Hancock, on behalf of Greensill. The company collapsed last month, threatening thousands of jobs at a British steelmaker that it helped finance.
