I find that I am having to continually compensate for a left sideways
putting more pressure on the right leg when pedalling  and by slightly
my upper body) - this is especially noticeable during long rides rathe
practice area.

I recently switched from a SEM 20' to a new DM 24 and  I  experience t
problem on the 24' but not on the 20' -  I have only been riding unis
weeks but the problem does not seem to have improved much after about
KMs on the 24'.  

I cannot detect any  misalignment of the seat, wheel, pedal, cranks et
obvious to the untrained *** eye.    The spoke tension on the 24 is
less than that of the 20' (ie there is some movement but I am unsure w
is excessive or not).    Presumably this may be a cause of the problem
there any rules-of-thumb to verify this ?  ....  any other ideas ?

Ahh, yes, I have seen this many times.  Your problem is simply that the

There could misalignment problems not obvious to the untrained eye.
Is the wheel dished out to one side or another?  (Spokes on one side
were tightened several turns more than the other side?)  One fork end
may be further from center than the other.

More obvious, but easily overlooked:  Are the wheel and seat pointed
in exactly the same direction?  Is the seat lop-sided in any fashion?

Try taking the cycle to a bicycle frame builder.  They may have the
equipment to really tell you if something is misaligned.
