Just got this from the Welsh Conservatives:
In a joint statement on the death of David and Samantha Cameron’s son Ivan, Shadow Secretary of State for Wales Cheryl Gillan MP and Assembly leader Nick Bourne AM said:
"We are devastated for David, Samantha and their whole family. They are devoted parents and we can only begin to imagine the scale of their loss.
"Our thoughts and prayers are with them at this terribly difficult time."
Politics Cymru also send our condolences to the Cameron family after their devastating news.
