We had the same thing last year. I put it down to insufficient water causing the die back. We cut off all the dead areas, gave the plants some feed...and the plants have thrived this year.
That could be root rot
I dont think lack of water could be an issue here, these plants where mature and well established, also, in northern ireland we never get more than 2 or 3 days without rain.

I thought it could have been vine weevil grubs eating the roots but the plants where quite large and sureley had a large enough root system to cope with this?

Too much moisture can cause root rot. Search web for aucuba phytophthora root rot
I don't think it's root rot as that would eventually affect the whole plant.
I seen similar and often thought it seemed to be linked to a sudden temp change...
Be careful about US website resources - sometimes their scenarios are unique to that geography.
I've seen similar on Photinias this year, in gardens prone to waterlogging. I'm hoping it's this, it makes sense that the roots are essentially drowning in the wet ground.
