Why have British farmers marched on UK’s Parliament?

Thousands of disgruntled British farmers marched on London on Tuesday in protest at government plans to change the law regarding the amount of inheritance tax farmers should pay.

The demonstrations saw tractors driven by farmers and coach loads of other agricultural workers from the United Kingdom’s four nations of England, Scotland, Wales and Northern Ireland descend on Parliament Square, to stage a large-scale protest in bitterly cold temperatures as leaders from the National Farmers’ Union (NFU) met with MPs at Westminster.
