Mike Hancock, MP for Portsmouth South has commented on the case of Ashya King who is from Southsea which is in his constituency.
Mike Hancock said: “I have contacted the Chief Constable of Hampshire Police and the Hampshire Police and Crime Commissioner asking them to ensure that the case is looked at very sympathetically as far as they are able to and Ashya is reunited with his parents as quickly as possible.
"While there might have been some uncertainty initially it has become clear that his parents have been acting in his best interests to try and get him the best possible medical treatment.
"I am also contacting Southampton Hospital and the NHS to ask them to look again at the options for his treatment and that they consider the treatments that Ashya's parents want for him.”
Hampshire Police has said Ashya King should be re-united with his parents at a "difficult and scary" time for him during his treatment.
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.
The parents of Ashya King said they took him out of a hospital to seek proton beam treatment which is not available under the NHS.
