An alarming decline in food production at British farms will leave shoppers at the mercy of prices and quality elsewhere in the world, warns a UK farming report.
The National Farmers Union has forecast a sharp rise in the amount of imported food as British farms convert into renewable energy sites and tourist attractions to stay afloat.
Minette Batters, deputy president of the NFU, said Britain was rapidly becoming less self-sufficient because support for domestic farming was considered less important by politicians who preferred to promote the "globalised economy".
Batters said the amount of home-grown food would reach new lows unless farmers received stronger backing from Westminster.
Britain was becoming increasingly vulnerable to global tensions, she said, and would develop a reliance on the co-operation of other nations in the same way that it depends on Russia and the Middle East for oil and gas.
