Almost half of Britain's private wealth owned by top 10% of households

Latest ONS survey covers 2012-14 and highlights gulf between country's richest and poorest groups

Britain's richest households have pulled further ahead of the rest of the population as house prices have accelerated, with the top 10% now owning almost half of the country's 11.1tn total private wealth.

The Office for National Statistics (ONS) said the average household was worth 225,100 in 2012-14, when it carried out its latest survey of the country's assets.
