2.5mm^2 is the standard for ring circuits. If you have a radial then 2.5mm^2 is good for 20A or 4mm^2 for 32A.
You don't need to match the fuse because a ring circuit feeds power from both sides, so (in an ideal perfectly balanced world) you'd only ever draw 15A through each leg.

Are you extending the ring circuit, or are you planning on spurring the new sockets from the existing ring?
Please provide us with as much informaton on your proposals as you can, so we can give you the most apropriate advice.

In which case 2.5mm^2 is fine. Remember to sleeve the earth with yellow and green sleeving and keep the cables in the safe zones (if you are chasing them into the walls).

I know.... 
I don't know how that happened...
But give me credit. I don't do it regularly.
Nor do I drag up old threads often.

Is that really a picture of BAS?
I don't think so. I reckon he would have more sense than to grasp that earth rod with one hand whilst touching something which 'looks live' with the otherIs that really a picture of BAS?
