Presumed garden escape

Observation - Presumed garden escape - UK and Ireland. Description: Habitat - alley adjacent to gardens. Large flowers vaguely daisy-like, approximately 15mm across and 18mm in length. I couldn't find anything with similar foliage to this but I'm sure someone will recognise it!?
