Ground Elder (Aegopodium podagraria) native to Eurasia, said to have been introduced to UK by the Romans . Very Invasive in garden beds. Very diffidcult to eradicate but can be dug out over several seasons ensuring that as much of the rhizomes and roots are remoced as possible. Regularly digging out will weaken any remaining roots over time. Remove any regrowth from pieces of missed Rhizome as soon as it appears.
