It is a dogwood and I am fairly sure that it is this one.

I guess in that case it must have self-seeded somehow. I'd thought it
might be a dogwood, but discarded the idea because there's so much of it
and it seems an odd thing to deliberately plant in a fruit/veg garden.
I guess it only takes one successful plant to have produced all the
others though.

While I think that it is a dogwood, that is conditional on it having
smooth stems. If it has bristly/spiny ones (minor spines only), then
my bet is Japanese wineberry, Rubus Phoeniculatus (or thereabouts).
Treat exactly like a blackberry or logan, and eat the fruits raw;
they are hopeless cooked, but do freeze successfully.

The stems definitely look smooth to me. What doesn't seem right for
a dogwood is that the ones I've seen have stems that fork, rather like
an enormous pepper plant. These don't appear have side-shoots at all.
