Numerous pieces of EU legislation are "outdated, disproportionate and not based on science", according to UK farming unions.

Stating that better regulation was needed to protect farmers, the four unions launched a joint manifesto in Brussels ahead of EU elections in June.

The unions said the EU must ensure its agricultural policies were necessary, practical and had passed impact assessments. Consumers also needed to be protected by a supply chain code of practice in which short-termism was ended, they added.
