The Haynes manual says check the plugs every 6000 miles and if worn excessively replaced.
Plugs wear by the electrodes being eaten away so there are no sharp edges.
This is most noticeable on the centre electrode.
I've got a feeling that which electrode wears depends on whether the car is positive or negative earth.
Also the insulation can break down but you need a special machine to see if this is happening.
Don't use plugs that are the wrong heat range for a Minor, that's another can of worms and could cause damage.
