Covid-19 vaccine: The story of how the EU felt pressure over the jab rollout

The BBC's Ros Atkins explains the events leading up to the EU Commission row over vaccines and the Northern Ireland border.

So the bloc announced it was introducing export controls on coronavirus vaccines made inside the EU to try to protect its supplies.
