OK, I've done a bit more investigating.
First, I can see something that looks as though this tool:
<http://www.parktool.com/products/detail.asp?cat=25&item=BBT-22>
will fit into. Does that give any useful information about what kind of
bottom bracket it is?
I have one of those tools in my toolset.
Unfortunately, I can't tell for certain whether it will fit, because I
can't get the cranks off. I have a crank-pulling tool, but having
tightened it as tight as it will go, nothing has budged.
Second, the axle is square - is this what is meant by a square taper? It
looks somewhat like this:

Finally, according to the Dawes website, newer versions of the same bike
are listed as having Shimano bottom brackets.
I don't know if this is useful in identifying what's likely to be on
there.
