Brett King, the father of Ashya King, has given an emotional press conference after his release from Spanish prison.
"Hopefully now we can see our son, we can be together and show love to him. Because without that there is no purpose to life," he said.
"We just want to help my son get through this bad time.
"Because he hasn't got too many months to live. And we were locked away in a cell and no one can do anything.
"We're just trying to speed things up to help him as much as possible."
