I have a set of unused red Oxford Sovereign soft panniers which I bought years ago and never got round to using. Just Google 'Oxford Sovereign Panniers' and you'll find pictures of the red ones. They're in perfect condition although a bit dusty from storage and have the straps and rain covers. £50.
I'm in Blantyre, so you're welcome to come and have a look to see if they are suitable.
Just drop me a PM.
