Dr Evan Harris, the Liberal Democrat MP for Oxford West and Abingdon, said: "The sad death of this little boy is shocking news and I offer my deep condolences to David and Samantha.

"Like many bereaved parents they will be very distressed at losing a child, but I am sure they will be comforted by the joy that his short life brought them and their family. I also hope they will be allowed privacy at this difficult time."
