Can anyone identify a tree for me? It has 2cm thorns, pictured at:

Forked thorns just like that are characteristic of _Carissa macrocarpa_
"Natal plum", in the family Apocynaceae. Does it have smallish, rounded
leathery leaves, milky white sap, white flowers, and possibly red
edible fruits, such as shown in:

Thank you, your description is spot on although my tree has never
produced any fruit. I've just had it removed because it had reached
the height of my house and its spikes were quite dangerous.
Thanks also for the links, some interesting material. The reference to
it as a hedge plant makes sense if you need a real deterrent hedge.
The guy who removed ours wore protective clothing and mask.
