When viewed closely the beetle seemed to have very short hairs all over apart from the wing.
No interactions present.
Many thanks Dioctria for your identification and to those who have confirmed it.
Looking at a field guide to beetles I see it says that of the 8 species of this genus in central Europe this is the only one found in Britain.
I have to thank my son for spotting it.
