Leonard Blavatnik

Investment, music and media mogul Leonard Blavatnik has a net worth of £19 bn, down £3bn on last year when he topped the list " richest people in the UK". He has a string of “glamorous businesses”, including “record label Warner Music and sports streaming provider Dazn”, The Guardian said last year. But the original source of his wealth was “energy and metals companies” formed after the break-up of the Soviet Union.

The Ukrainian-born billionaire also made “billions by buying out heavy industrial companies, including the Texan chemicals and plastics company LyondellBasell and Calpine, which runs gas-fired power plants”, the paper added. When it was sold to Russia’s Rosneft in 2013, Blavatnik’s share was worth more than £4 billion. He also invests in aluminium producers and chemical companies, as well as the world's largest producer of polypropylene LyondellBasell. In 2011, he bought Warner Music and then The Beatles' label, Parlophone.
