I've previously found what I thought were Chafer beetle grubs whilst digging in the soil of my garden borders, but this time I'm certain. Those little legs at the top and the overall shape give it away – at least as far as my best internet research tells me and it may be a Cockchafer, being about 35mm long.

They live in the soil for several years chewing at roots and potentially causing visible surface damage to lawns and plants, before emerging as an adult beetle that only lives a few weeks before laying eggs deep in the soil and starting the cycle again.

Quite the beastie to discover if you weren't expecting it!
