Bought some sockets today, put the 2.5mm in, tightened the screw, the

What would a proper electrician do in this circumstance?
I folded the cable double but not really happy. Is this a common 'problem'?

I thought that was how you should do it. The space is to allow
ring main in and ring main out, plus possibly a cable to a single
socket spur. I'd be more annoyed if there wasn't anough space to allow
this.

Wouldn't mind if i'd got them at the pound shop but they came from an
electrical wholesaler.
