Polish border blockade leaves Ukraine's farmers sitting on grain

Ukrainian farmer Lyudmyla Martyniuk's grain should be on its way to export.

Instead, it's sitting in silos, prevented from travelling by a farmers' blockade at the Polish border.

"This is unacceptable" she says, echoing the word's of Ukrainian President Volodymyr Zelensky who in February decried the actions being taken against his war-torn country.

Many EU farmers say the influx of Ukrainian grain has led to a collapse in prices and are calling on the EU to toughen import rules.
