Shortly after his return to London, Marks founded the
Financial and Mining News (later simply the
Financial News) on 23 January 1884, with financial backing from an American, Colonel
Edward McMurdo. He later floated the paper on the stock market in 1885 at a valuation of £50,000, reconstructing the company in 1890 to raise £100,000, whilst retaining a controlling interest throughout. The
Financial News was a major step forwards for British
financial newspapers; it was the first London financial paper to publish on a daily basis, and pioneered a popular, Americanised, accessible style of writing that appealed both to the industry professionals and to small private investors. The
Financial News was active at
investigative reporting, exposing a number of fraudulent share schemes as well as playing a part in the corruption scandals that led to the downfall of the
Metropolitan Board of Works in the late 1880s. As a result, it achieved a good reputation for integrity and honesty, widely respected among small investors. His contemporary
Frank Harris later summed Marks up as a man of "few scruples and many interests"; nowhere was this more clear than the way in which he exploited his paper's reputation for his own commercial schemes. His first major fraudulent venture was the Rae-Transvaal Gold Mining Company, formed to cash in on a boom in South African mining stocks. Marks had bought a farm in the Transvaal for £10,000, promptly selling it on to a newly created shell company at a notional value of £50,000. He then floated it in January 1887, with the
Financial News stoking up enthusiasm for the stock. As the stock prices inflated, helped by the paper publishing fictional values, Marks sold out; the company was wound up in May 1888, by which time it had become apparent the Rae mine – and the company itself – was worthless. In 1890 he sued two journalists for libel over a pamphlet exposing his involvement in the matter. After an eight-day trial in which Marks' less salubrious past was extensively debated, the jury held that the content of the pamphlet was true, and that publishing it was justified in the public interest; Marks was forced to pay costs. ==Political career==
