Hundreds of tractors block Westminster

Farmers from across the UK have driven to London to protest against changes to inheritance tax.

In October, the government announced it would charge a 20% inheritance tax on agricultural assets worth more than £1m for the first time, although the threshold for some farmers to pay will be £3m.

The change has sparked fierce opposition from farmers, who say it will "ruin" farms and push food prices up.

The government has said no tax would be payable on the first £325,000 above the limit - bringing the untaxed total to £1.325m.
