Carl Bildt, former prime minister of Sweden, shares his perspective on European politics - this week from the airport in Madrid.

What are the consequence of the dispute now between Ukraine and the European Union on farm exports?

It is not really a dispute with the European Union because the commission has said that farm exports are okay. But then suddenly Poland has an election, and Slovakia which has election and Hungary, which has own policy, said, “No, no, we don't allow these particular grain exports from Ukraine because our farmers don't like it.” That runs totally contrary to the common trade policy that the European Union is running, runs totally contrary to the solidarity with Ukraine and support to Ukraine that we have all agreed on. So yeah, we'll see what happens. It’s a serious question.
