Blairmore Holdings, Inc. was an offshore investment company established by , father of former British Prime Minister, David Cameron. Following the Panama Papers leak, it was discovered that Blairmore Holdings was a customer of Mossack Fonseca, a large Panamanian law firm and corporate service provider at the centre of an international scandal on tax havens, tax avoidance and corruption.
Blairmore Holdings is still in operation and has assets of £35 million.
Blairmore Holdings is company operated as a collective investment fund, in which a range of individuals invest collectively in the and other financial instrument. Blairmore Holdings was established in 1982. The company is named after Blairmore House in Aberdeenshire, the house in which the stockbroker – father of UK Prime Minister David Cameron – was born.
The company was incorporated in Panama, but based in the Bahamas. According to the Financial Times: "The idea was for investors to avoid an extra layer of tax because investors came from lots of jurisdictions and some, at least, would have faced double taxation if the fund had been based in a mainstream jurisdiction — firstly by the country where the fund operated, and then by the investor's own country when he or she received his profits." The company was created after the abolition of capital controls by Margaret Thatcher in 1979, which allowed UK individuals to invest outside the UK without first obtaining permission from the government.
Ian Cameron ran Blairmore for thirty years alongside 5 other UK-based directors. The fund retained up to 50 Caribbean officers each year; their job was to sign paperwork and fill roles such as treasurer and secretary, to ensure that the company was not centrally managed and controlled in the UK, and so maintain its tax residence outside the UK. They included the late Solomon Humes, a lay bishop with the non-denominational Church of God of Prophecy. From 2002 until 2007, the fund averaged 116% annual returns, holding in Apple Inc., Unilever and Coca-Cola.
