British families’ inheritance tax bill has risen by more than 90 per cent since 2010 and become a "general tax on middle England", experts have warned.

The amount that the Government raises from inheritance tax has risen from £2.47billion to £4.72billion under the Conservatives, according to a new analysis by private client law firm Wilsons.

It found that the Treasury has become increasingly dependent on inheritance tax, which has nearly doubled as proportion of the taxman's overall income from 0.5 per cent to 0.87 per cent.
