Ashya King's parents are facing another night in their prison cells because the application to withdraw the European Arrest Warrant for them in England has not been formally approved yet.
However, it seems the Spanish prosecutor here has decided to act independently of what is happening in the UK.
I'm told he is going to ask a judge tomorrow to free the couple on bail, and they are due before that judge in the morning.
He will have to approve the request, but I am told the prosecutor's opinion is usually upheld.
So it could mean Ashya's parents could well be by his bedside this time tomorrow.
Ashya King's parents told the Daily Mail they fled the UK after being told NHS treatments would leave him with life-long disabilities.
The head of the police force which applied for a European Arrest warrant against the parents of Ashya King has now urged their release.
A British mother whose son's life was saved by proton therapy has told ITV that she defied NHS doctors' advice to pursue the treatment.
