A London-based Ukrainian businessman has topped a list of Britain's richest people.

The Sunday Times Rich List shows that the collective wealth of Britain's richest people has more than doubled in the last 10 years.

Len Blavatnik, whose empire includes the Warner Music Group, was at the summit this year, with an estimated fortune of £13.17 billion.

Mr Blavatnik took over top spot from brothers Sri and Gopi Hinduja, who were nudged into second despite their fortune rising by £1.1 billion to £13 billion.

Galen and George Weston and family, who run a retail empire including Selfridges and Primark, enjoyed a particularly prosperous year, with their wealth soaring by £3.7 billion to £11 billion.

Steel magnate Lakshmi Mittal and Chelsea Football Club chairman Roman Abramovich saw their fortunes fall by £1.05 billion and £1.23 billion respectively, the list claimed.

However, neither are likely to be sweating too much over their finances. Mittal and family are still worth an estimated £9.20 billion while researchers put Abramovich's fortune at £7.29 billion.

The list charts wealth including land, property, assets or significant shares but excludes bank accounts.

The top 25 are:

1 Len Blavatnik £13.17 billion

2 Sri and Gopi Hinduja £13 billion

3 Galen and George Weston and family £11 billion
