Tiny, red leaf beetle

Observation - Tiny, red leaf beetle - UK and Ireland. Description: Very small beetle (maybe 2-3mm long) on thick leaves. I thought for a moment it was a mite - bigger

Very small beetle (maybe 2-3mm long) on thick leaves. I thought for a moment it was a mite - bigger than that but much smaller than a ladybird.
Shiny, copper-red all over, apart from prominent black eyes. After some research 'Sphaeroderma' looks close but due to poor quality of images I do not hold out much hope for a definite ID
