The plans, which had been heavily leaked, were presented on Wednesday by the EC's Dacian Ciolos. They propose to distribute funds more fairly by capping payments and to 'green' the CAP through environmental incentives.
The NFU and CLA said the proposals marked a "missed opportunity" to set agriculture up for a sustainable future and that they would disadvantage English farmers. In a statement, they said they would "do everything possible to improve the proposals".
The WWF said the EC's 'greening' measures were too "weak" to encourage a change to more sustainable practices. Green MEPs also said the 'green' proposals had been "watered down" to pander to the "agro-industry lobby" and unco-operative member states.
