Italy’s top court threw out Amanda Knox’s conviction for the 2007 murder of British student Meredith Kercher, bringing a sensational end to an eight-year legal drama that has gripped a global audience.

Judges at the Court also quashed all charges against Knox’s Italian ex-boyfriend Raffaele Sollecito after 10 hours of deliberations in Rome.

“I am tremendously relieved and grateful for the decision of the Supreme Court of Italy,” Knox said in a statement from her home in Seattle.

The 27-year-old, had served four years in prison before being freed on appeal in 2011.

The knowledge of my innocence has given me strength in the darkest times of this ordeal.

Sollecito, 31, learned of the verdict at his home in Puglia in southern Italy, where he had driven after attending the final hearing in the high court review on Friday morning.

Finally I can resume my life. I still can’t quite believe it. Finally I will no longer have to spend all my time with legal papers. I can return to normal.

- Raffaele Sollecito

The shock verdict was greeted with chaotic, jubilant scenes in the great hall of the Roman courthouse.

Chairs went flying as Sollecito’s lawyer Giulia Bongiorno reacted to the shock verdict by shouting “yes, yes, yes” and leaping up and into the arms of a colleague.

“Raffaele has been a rock. This verdict has proved him completely right,” she said.

Knox and Sollecito believed they had been freed to resume their normal lives when they were first acquitted in 2011.

But that decision was found to be flawed by the Court of Cassation in 2013, leading to a retrial in Florence which reinstated the initial convictions last year and increased Knox’s sentence to 28 years and six months.

I would have had to be dragged back kicking and screaming into a prison I didn’t deserve to be in.

Lawyers for both defendants said they would be seeking compensation for the time spent in prison - two years on remand before their initial conviction and two more before they were freed on appeal.
