The parents of cancer patient Ashya King say they will not return to the UK because they still fear the authorities may take their son away from them.

Speaking to Sky News in Prague, Brett and Naghmeh King said they plan to continue Ashya's treatment in Spain and will not return to Britain until they are satisfied it is "safe" to do so.

The five-year-old's parents sparked a Europe-wide search when they took him out of a Southampton hospital without medical consent.

Ashya, who was being treated for a brain tumour, has been well enough to play with toys as his treatment at a state-of-the-art therapy centre in the Czech Republic comes to an end today.

He  is completing the last of his 30 sessions of proton beam irradiation at the Proton Therapy Center (PTC) in the Czech capital, six weeks after starting treatment.

Staff at the clinic say he is making good progress and is even well enough to have attended a special end-of-treatment party with his family and medics at the centre.
