She overcame Mira Potkonen, who was hotly tipped for a medal, in the semi-final.
Speaking ahead of the fight, the 28-year-old said: “Let's go ahead, let's get on the podium, at the top and listen to our anthem ring out. It will be difficult [for Harrington] to take it away from me. I trained for this moment.”

She won the title in 2019 in Russia, with Harrington missing out on that tournament due to injury.

What does Harrington say?
