Farmers with tractors demonstrated tonight outside the British Parliamentprotesting the trade agreements in place after the Brexit and substandard food imports, they argue.

At least 50 tractors, many of them flying the British flag, took part in the rally. “No farmers, no food, no future” were written on some signs held by the gathered.

The farmers they are asking the government to enforce more accurate food labeling and take steps to improve the country’s food security. They also want an end to trade deals which they say allow food produced to standards that would be illegal in Britain to be imported, thereby undermining local producers.

“They let us down again and again,” she said Liz Webster, the founder of the organization “Save British Agriculture” speaking to the BBC. “They promised to maintain high standards and not allow Britain to become a dumping ground (…) what they are doing is turning us into a dumping ground,” he argued.

Farmers across Europe have mobilized in recent months, protesting competition from cheaper imports and calling for stricter environmental rules.
