MLAs pay tribute to 'wee Oscar' Knox
MLAs paid tribute to five-year-old Oscar Knox who died on 8 May after a two-and-a-half year battle with neuroblastoma, on 12 May 2014.
His family launched the Oscar Knox Appeal campaign during his illness to raise awareness of the condition.
First Minister Peter Robinson remembered Oscar's "mischievous innocence" the day he and the deputy first minister met the little boy.
"You couldn't have been in his presence without smiling," he said.
He offered condolences to Oscar's family.
Deputy First Minister Martin McGuinness also remembered the day Oscar came to Parliament Buildings.
"He was like an Exocet missile running through the building, and we loved it," Mr McGuinness said.
"We have to be more united because he was a uniter," he added.
The SDLP's Joe Byrne said Oscar had been "a person of great inspiration", and he paid tribute to the boy's parents for their fundraising efforts for cancer research.
Ulster Unionist Joanne Dobson said "Oscar Knox was Northern Ireland's wee superhero".
Alliance leader David Ford said Oscar had "touched the lives of people right across Northern Ireland" and paid tribute to "the leadership we have been shown by a five-year-old".
Steven Agnew of the Green party said the rarity of Oscar's illness meant he was "one in 10m".
He said that as a father of a five-year-old he knew how much joy and how much work children of that age could be.
