A Ukraine-born, U.S.-educated record label owner is now the richest man in Great Britain. Atop this year's Sunday Times rich list is Warner Music Group owner Len Blavatnik, who jumped from No. 4 to No. 1 in one year's time after increasing his worth from $4.8 billion in 2014 to an estimated $20 billion.
Blavatnik purchased Warner Music in 2011 for $3.3 billion. WMG's portfolio includes Atlantic, Warner Bros. Records, Rhino and Warner Music Nashville, along with publishing services from Warner/Chappell and other companies. Two years after buying WMG, Blavatnik picked up Parlophone, bringing Coldplay, Blur and others to WMG.
