Britain's richest man isn't even British - it's Ukraine-born billionaire Len Blavatnik.
Blavatnik is worth $20.1 billion, rising to prominence after his privately held industrial group, Access Industries, purchased Warner Music Group for $3.3 billion in 2011.
Since investing in tech giants Spotify and Beats, his wealth has ballooned, propelling him to the top spot from the number four spot on the Sunday Times Rich List just last year.
