The number of millionaires in the UK has risen by 41 per cent over the past five years because of booming house prices and stock market gains, figures show.
There are now 715,000 millionaires living in Britain compared with 508,000 in 2010. Of the new millionaires over the past five years, 48 per cent live outside London and the South East, the Barclays UK Prosperity Map shows.
Its prosperity index found that Reading, Cambridge and Birmingham are the most affluent cities outside London, while the east of England is the third most prosperous area.
