Access is only from above. The screw is in a recess, and close to
a raised surround, making it pretty tricky to get at. Removing

to be a self tapper about 20 mm long.

How about a diamond tipped screwdriver blade? Apply a lot of pressure and
who knows, you might get lucky.

Full marks to that man! It worked a treat. Now I just have to
find time to complete the task and start fault-finding.
