Britain's millionaires are some of the youngest in the world with an average age of just 55, a survey of the super-rich has found..........

The UK sits well below the likes of France, Germany and America and beats the global average age of 57.

It also has some of the youngest multimillionaires - those with $30 million (£19 million) or more - with an average age of 57 compared to the global average of 60 years of age. 

Some of Britain's youngest millionaires include Adele with a fortune of £30million and 17-year-old Nick D'Aloisio who sold his app Summly for £15million.

The figures mean Britain has the second youngest average age for both millionaires and multimillionaires in the G8 and the third youngest in the G20 after both Russia and China.

Millionaires and multimillionaires tend to be younger in the UK than elsewhere in the Western world because of several factors, says Spear's magazine which carried out the research in association with leading wealth consultancy company WealthInsight. 

Spear's editor Josh Spero said: 'First, we have a long history of entrepreneurialism, building companies which grow to span the world.

'Whether these have been industrial bus

'Second, young Britons are often developers and early adopters of technologies, seizing on their potential for business. 

'Finally, we share an approach to business with America, where we try and encourage people to make it rather than wrapping them up in red tape and strangling them with high tax rates, as too often happens in Europe.'

The average age of millionaires and multimillionaires reflects deeper trends in society.

'Western countries, with greater access to technologies, will be creating millionaires younger too as they take advantage of these new fields of business.'Japan and Italy have an ageing population who live longer and keep hold of their money longer, preventing it flowing down to successive generations, whereas Russia experiences a free-for-all after the Soviet Union collapsed and opportunistic young businessmen acted quickly to get hold of state assets.

'I hope we see Africa starting to produce generations of millionaires. Its population is young and booming, giving vitality and innovation and a huge potential market. 

'Now that technology is reaching Africa much more effectively, its younger generations will be able to bring its benefits to the continent through smart start-ups. 

'Added to this is the continent's growing middle class, who need products and services, which businesses will spring up to provide.'

Argentina has the oldest average age of millionaire and multimillionaire in the G20 at 67.8 and 68.1 respectively, reflecting the economic crisis of the 1980s and 1990s which prevented young millionaire and multimillionaire growth.

According to Oliver Williams, an analyst at WealthInsight, these statistics could well change over the next decade. 

'We're likely to see a lower average age of millionaires in the UK as 452,000 new millionaires enter the picture between now and 2017.'

However, it is not the same story for Russia:

'The average age difference between millionaires and multimillionaires in Russia - already above average - will further separate as the original oligarchy hold on to their empires into old age.'
