- Watch as Lisa Dunn finds out her brother Nick has been acquitted
The family of Nick Dunn, from Ashington, Northumberland, gathered together as they waited to hear if the news was good.
Sipping champagne, his sister, Lisa, said: "This is the best champagne in the world, it tastes like the best drink.
"The longer it went on, as much as you still have an element of hope, it does dwindle after having so many delays and setbacks.
"But that hasn't happened today and we've had the best news ever.
"It will make all of our Christmases, all of our dreams have come true today."
Mr Dunn's father, Jim, said: "Absolutely fantastic, the best news in the world.
"We haven't been a full family for a long time now. Nick won't fully realise it's over until his feet touch down in Newcastle."
