If its just side to side movement along the plane of the swingarm pivot then its more than likely you can re-shim the swingarm, you may find original shims have corroded and fallen apart
There are a couple of different thickness shims available so if it needs doing work out wat you need first

Many thanks for all the replies all, it's much appreciated.
I'll try to keep this short - the MOT guy reckons it's dodgy bearings in the swingarm because when he grabbed hold of the top and bottom of the rear tyre and yanked it about there was a very slight clonking noise. He ruled out the rear wheel bearing and then thought it was the swingarm bearings and failed it. I had it all apart last night, there's definately no play in the rear wheel bearings or in the swing arm. Put it all back together and the noise was still there, took the brake caliper off and lo, noise gone! Does this make any sense?
Hopefully I can convince the MOT man this morning without having to take it off to prove it! Does seem a bit of a strange one as when everything at the back end is bolted up it should all move as one I spose but it does seem as though the bracket the caliper is bolted on can move around a wee bit...
thanks again,
A.

The rear caliper mounting bracket sounds to be the culprit here, there is a stud that sticks out of the inside of your swinging arm, your caliper mounting bracket uses this stud to stop the caliper rotating with the wheel when the rear break is applied. So if the tester grabbed the wheel to check the bearings then the mounting bracket could move and cause the clacking sound.
