How do I open this radio up please, so that I can fit the earphone
socket that Sony fits as standard on all units except those sold in the UK?

I've taken the 5 screws out, and it opens 20mm at the back, but really
does not want to separate at the front.....

Look for other screws hidden under sticky labels, and also plastic
latching clips between materials. Sometimes you may have to accept
colateral damage in performing the operation. A little heat from a
hairdryer may help soften the plastic a bit. Just go slow!
