The 24th annual Sunday Times Rich List – the “definitive” guide to wealth in Britain and Ireland – is published on Sunday, April 29 in an extra 104-page magazine, which profiles the 1,000 richest people and families in the UK and the 250 wealthiest in the island of Ireland. The list is based on identifiable wealth (land, property, other assets such as art and racehorses, or significant shares in publicly quoted companies), and excludes bank accounts (to which the paper has no access).
The Sunday Times Rich List 2011 is compiled by Philip Beresford, the leading authority on British wealth, and edited by Ian Coxon.
