Bit hard from that distance, but could be Geranium robertianum.

Be about my best guess also, Ob.

If it stinks when you touch it, it is. I think it may also be called Herb Robert and it pops up everywhere in my garden.

Many thanks for you replies. I'll try and get a better photo in the summer.

Definitely Herb Robert. Pretty but a darned nuisance. Welcome to GoY, Mebian. That's a lovely noticeable avatar you have there!

Gattina, thank you for your welcome and the other comments. When looking at my avitar, I hope you had your sun glasses on. Regards, Mebian
