Rhagium Bifasciatum...

...in English - Two Banded Longhorn Beetle...

More Googling to find out what it is!  It was about an inch long.

I actually took my camera today!  Got lots of bugs...  It stopped trying to focus again today so given I am using my dad's macro lens, it turns out it must be my camera and not my lens that is the problem!  My dad will have a look at it at the weekend.
